Evaluation Of The Failure Probability Of Slopes In Residual Soil From The Aburrá Valley, Medellín Colombia, Juan Pablo Villada Rodas, Manuel Roberto Villarraga
Evaluation Of The Failure Probability Of Slopes In Residual Soil From The Aburrá Valley, Medellín Colombia, Juan Pablo Villada Rodas, Manuel Roberto Villarraga
International Conference on Case Histories in Geotechnical Engineering
In recent years the evaluation of failure probability on slope stability analyses has become important because it has been presented as a representative method helping to complement the factor of safety. As part of this paper, it is proposed the evaluation of the failure probability in cut slopes on residual soils from the Aburrá valley. Statistical analyses were performed on the most important variables, considering continuous statistical distributions. Sensitivity analyses were performed to quantify their influence in the stability. As a result, some abacuses are developed in which the height and the slope angle are related to the failure probability …

Historical Application Of Screw-Piles And Screw-Cylinder Foundations For 19th Century Ocean Piers, Alan J. Lutenegger
Historical Application Of Screw-Piles And Screw-Cylinder Foundations For 19th Century Ocean Piers, Alan J. Lutenegger
International Conference on Case Histories in Geotechnical Engineering
Iron Screw-Pile foundations were first introduced by Alexander Mitchell in the middle of the 19th Century for support of offshore lighthouses in shallow water ocean environments. Large diameter Screw-Piles with helical blades ranging from 2.5 ft. to 4 ft. in diameter were routinely used during this period and were constructed with either a solid iron central shaft (Screw-Pile) or a large diameter hollow cylindrical pipe shaft (Screw-Cylinder). Soon after their introduction, Screw-Piles and Screw-Cylinders were being used in pier construction, to allow ocean front piers to be constructed quickly and economically in many parts of the world, while at the …

A Case Study On The Use Of Flexible Earth Retaining Structure In Instable Slopes, H. Turan Durgunoglu, Ahmet Sahin, Onder Akcakal
International Conference on Case Histories in Geotechnical Engineering
Recently new highway, motorway and railway projects take place in many developing countries within the aggressive infrastructure investment programme of governments. In rugged topography, engineers face the challenging problems of designing safe and cost effective cuts and fills for these projects especially under seismic loading and marginal stability conditions. Overall stability mechanism and safety of the cut generally controls the design decisions for the relevant section. In addition, because of the construction width limitations, in some mechanically stabilized earth wall projects sufficient width to accommodate the strip lengths of the retaining system cannot be provided. To eliminate all these problems, …
Liquefaction Of Mine Tailings, Vijay K. Puri, Todd R. Kostecki
Liquefaction Of Mine Tailings, Vijay K. Puri, Todd R. Kostecki
International Conference on Case Histories in Geotechnical Engineering
Liquefaction of mine tailings is known to occur during cyclic, quasi-static & static loading cases but is still a relatively misunderstood concept because tailings dam failures continue to occur. In the worst case scenario the results are high costs, hindered public perception, environmental cleanup and worst of all, the loss of life. A better understanding of this issue is essential for any engineer associated with the mining and/or geotechnical industry, and in particular tailings dam construction and maintenance. This paper presents the liquefaction concept, some case histories dealing with failure of mine tailings dams, available testing methods and some dated …

International Conference on Case Histories in Geotechnical Engineering
The city of Hyderabad is a part of lower Indus Basin with arid-tropical climatic conditions. Geologically, the soil deposits near Hyderabad are of alluvial-loessic nature underlain by limestone beds alternating with clay layers. Groundwater is present at shallow depth which fluctuates to even shallower depths during monsoon season in the months of July and August. In recent past, large number of buildings built over shallow foundations in the city suffered structural damages of varying scale in the form of cracks and settlements. Some of these buildings were declared dangerous from safety and stability view point and got vacated by local …

Punch-Through Foundation Failure Of Oil Drilling Platform In The Deltaic Plain Of The Niger River, E. A. J. George, T. J. Atuboyedia, M. Oju, T. E. George
Punch-Through Foundation Failure Of Oil Drilling Platform In The Deltaic Plain Of The Niger River, E. A. J. George, T. J. Atuboyedia, M. Oju, T. E. George
International Conference on Case Histories in Geotechnical Engineering
The deltaic plains of the Niger River are composed mostly of Pleistocene sediments. On the occurrence of low stands of the sea level due to eustatic changes, the sediments were exposed to temperature fluctuations during the Quaternary period, leading to strata sequence generated in these plains that allowed strong layers of soil to overlie weaker layers of the same age. Most of the onshore explorations for oil and gas in Nigeria take place within these plains of the Niger. A well was to be drilled in search of oil and gas in allocation within these plains. As often done, a …
Damage On A Main Gas Pipeline Due To Landslide Of Soils Derived From Volcanic Ashes In Colombia, Gilberto Ch. Rodriguez, Julián V. Rodriguez, Natalia A. Quintero, Jorge E. Villamarín
Damage On A Main Gas Pipeline Due To Landslide Of Soils Derived From Volcanic Ashes In Colombia, Gilberto Ch. Rodriguez, Julián V. Rodriguez, Natalia A. Quintero, Jorge E. Villamarín
International Conference on Case Histories in Geotechnical Engineering
In December 2011 a great proportion slope failed affecting the main gas pipeline (20” diameter) that supplies Colombia’s southwest area. The landslide involved materials formed by soils derived from volcanic ashes and residual soils, typical in Colombia’s central zone, which acquired great energy flowing in an avalanche through the natural watercourse. The avalanche generated soil erosion over the torrent banks, generating the watercourse deepening and the deterioration of adjacent slopes over which the pipeline runs. There were identified as landslides triggering aspects the atypical raining period due to “La Niña” climatic phenomenon and the soils removal at the slope base …
Case Study Of Landslides In Kabylia Region, Algeria, Sadaoui Omar, Sadaoui Samir, Bahar Ramdane
Case Study Of Landslides In Kabylia Region, Algeria, Sadaoui Omar, Sadaoui Samir, Bahar Ramdane
International Conference on Case Histories in Geotechnical Engineering
Kabylia is mountainous and coastline region of Algeria. Every year, particularly in the winter, it is affected by landslides displacing an important volume of detritic materials, and causing damages to infrastructures, housing and public facilities. It takes place in geological formations that are particularly favourable to this type of movement, because of the heterogeneity of their facies and the impermeability of some layers. Experience shows that the main cause of the landslides in this region is the combination of several passive and active factors, as geology, morphology, hydrology, climate and anthropic activities. The exceptional rains of winter 2012 triggered a …

Dynamic Properties Of Stabilized Subgrade Clay Soil, Argaw Asha Ashango, Nihar Ranjan Patra
International Conference on Case Histories in Geotechnical Engineering
Expansive soils are fine-grained soils that can undergo a significant volume change due to the variation of water content. A change in the water content of weak subgrade material under the roadway is a cause for the damage of the road pavement. During an earthquake, the soft clay will lose the small shear strength it possesses which causes cracks and movements of the road. In the present study, soil samples were collected from Banda, Uttar Pradesh, India. The study area is at risk for seismic damage due to Himalayan frontal fault earthquakes. The soils samples are highly expansive in nature …

Investigating Failure Of A Geosynthetic-Reinforced Soil Wall In Black Hawk, Colorado, Jonathan T. H. Wu, Kanop Ketchart
Investigating Failure Of A Geosynthetic-Reinforced Soil Wall In Black Hawk, Colorado, Jonathan T. H. Wu, Kanop Ketchart
International Conference on Case Histories in Geotechnical Engineering
Approximately 18 months after construction, an 11-m high rock faced Geosynthetic-Reinforced Soil (GRS) wall was found to suffer from subsidence of about 100 mm on the crest, along with rocks being dislodged from the wall face from time to time. In the ensuing three months after these signs of problems were first detected, the subsidence on the crest of the wall increased to about 250 mm with significant lateral bulging on the wall face. The wall comprised two sides. The problems occurred primarily on one side of the wall; while the other side showed little distress. The entire wall eventually …

By stipulating this inclusion ECSA acknowledges that engineering can no longer be regarded as a neutral, apolitical endeavour. This paper responds to the latter position and sets out to offer a broadening of the current scope of scholarly dialogue between a logical science and the human community which it serves. In …
Microbiological Improvement Of The Physical Properties Of Soil, Edward Kavazanjian Jr., Ismail Karatas
Microbiological Improvement Of The Physical Properties Of Soil, Edward Kavazanjian Jr., Ismail Karatas
International Conference on Case Histories in Geotechnical Engineering
The application of microbiological processes for improvement of the physical properties of soils offers the promise of sustainable, cost effective, non-disruptive ground improvement for a variety of geotechnical problems. Potentially beneficial applications of microbiological processes include increasing the stiffness of soil to reduce settlement and lateral deformations, increasing shear strength to enhance foundation bearing capacity and slope stability and to facilitate excavation and tunneling, reducing the susceptibility of granular soil to earthquake-induced liquefaction, reducing swell (expansion) potential of fine grained soil, and reducing permeability for groundwater control. Microbiological processes that can potentially be employed for these applications include mineral precipitation, …

Evaluation Of Damage To A Road And Sports Complex On Expansive Clays, M. B. Mgangira, P. Paige-Green
International Conference on Case Histories in Geotechnical Engineering
The paper discusses a road rehabilitation project and a sports complex, where the underlying in situ materials were typical African black cotton soils known for their expansive characteristics. Field investigations were undertaken to discern the main causes of the pavement distress and the serious damage to roads and structures encountered at a large sports complex with the support of quantitative data from test pits and with laboratory test results. In addition, available design documents and construction records were reviewed to identify key aspects that may have contributed to the observed excessive cracking of the road pavement and damage to both …

Recent Experience On Design, Construction And Performance Of Cfrd Dams, Camilo Marulanda Escobar, Alberto Marulanda Posada
International Conference on Case Histories in Geotechnical Engineering
The inherent features of concrete face rockfill dams and the trend of building higher dams have been recently questioned by three recent incidents where major dams have experienced significant cracking in the central portion of the dam after the first filling. The incidents include the dams of Mohale in South Africa, and Barra Grande and Campos Novos in Brazil, the last one being the highest dam of its type built in the world. The design and development of CFRD dams, have been based primarily on precedent and empiricism, however, these recent incidents have shown that the extrapolation of precedent with …
