Incorporating Spatial Data And Gis To Improve Sea Of Land Use Plans: Opportunities And Limitations: Case Studies In The Republic Of Ireland, Ainhoa Gonzalez Del Campo
Incorporating Spatial Data And Gis To Improve Sea Of Land Use Plans: Opportunities And Limitations: Case Studies In The Republic Of Ireland, Ainhoa Gonzalez Del Campo
Doctoral
This research aimed at establishing whether spatial data and Geographic Information Systems (GIS) can contribute to Strategic Environmental Assessment (SEA). To achieve this, an integrated GISEA approach was developed and applied to a number of spatial planning SEAs in the Republic of Ireland. The practical applicability of the approach was examined, evaluating the potential benefits derived from using spatial data and GIS in SEA and assessing the potential barriers to an effective GIS use. The implementation of the SEA Directive incorporated a new dimension into plan-making by calling for the assessment of potential environmental effects that may derive from implementing …
Site Response Zones And Short-Period Earthquake Ground Motion Projections For The Las Vegas Basin, Barbara Luke, Ying Liu
Site Response Zones And Short-Period Earthquake Ground Motion Projections For The Las Vegas Basin, Barbara Luke, Ying Liu
Civil and Environmental Engineering and Construction Faculty Research
A deterministic seismic hazard analysis was conducted to address the effect of local soil conditions on earthquake-induced strong ground motion in the Las Vegas Basin, Nevada (US). Using a large geological and geotechnical database, two response units were defined: a fine-grained unit, predominantly clay; and a coarse-grained unit, predominantly gravel. A moderate number of high-quality shallow shear wave velocity measurements were collected from which characteristic shear wave velocity profiles were developed for each response unit. An equivalent-linear one-dimensional site response model was used. The model was calibrated using a basin-wide, small-strain ground motion database. Calibration tests showed that ground motion …
Strategic Approaches For Management Of Risk In Geomechanics, R. Chowdhury, P. Flentje
Strategic Approaches For Management Of Risk In Geomechanics, R. Chowdhury, P. Flentje
Faculty of Engineering - Papers (Archive)
This paper outlines the challenges facing geomechanics and advocates some strategies for dealing with these challenges. Advancement of geomechanics and its application in the past may be seen in a historical context as serving the needs of society such as the development of infrastructure and natural resources. The needs of society are changing rapidly due to population growth, increasing urbanisation and globalisation. Climate change poses specially challenges, the impacts increasing with time. Therefore, development of new strategies is essential. For example, greater attention should be given to the development of interdisciplinary approaches. It is vitally important that systematic methods be …

General Report — Session 11: Application Of Case Histories In Education And Practice, Sanjeev Kumar
International Conference on Case Histories in Geotechnical Engineering
Geotechnical engineers frequently use information about subsurface conditions from other projects in the area to design new projects in the vicinity. However, this information is used more in a surfacial manner rather than an integral part of project design. This session on application of case histories in education and practice has been introduced for the first time in this conference to initiate formalization of the use case histories in engineering design and training of civil engineering students. This report summarizes the papers submitted by various civil engineering educators and professional practitioners. The readers are encouraged to review the complete papers …
The Impact Of Low Probability Ground Motions On Canadian Geotechnical Engineering Practice, W. D. Liam Finn
The Impact Of Low Probability Ground Motions On Canadian Geotechnical Engineering Practice, W. D. Liam Finn
International Conference on Case Histories in Geotechnical Engineering
The adoption of design motions with a 2% rate of exceedance in 50 years in the National Building Code of Canada (NBCC 2005) has had a major impact on geotechnical engineering practice in Canada. The peak ground accelerations were doubled compared with the previous motions which had an exceedance rate of 10% in 50 years. The increase in accelerations has had a huge effect on assessments of liquefaction potential and slope stability, because the methods of assessment in common use depend on peak ground acceleration. This paper describes typical problems encountered in Canadian practice with use of the low probability …

A Field Test Study On Instrumented Soil Nail Installed In Cut Slope, A. K. L. Kwong, C. F. Lee
International Conference on Case Histories in Geotechnical Engineering
Soil nailing is a technique routinely used in Hong Kong whereby closely spaced steel bars are installed into a slope so that its stability conditions can be improved. A full-scale field test has been carried out by The Department of Civil Engineering of The University of Hong Kong to study the development of passive load along the full length of soil nails when subjected to induced rise in groundwater table. The cut slope was formed to a very steep angle of 55° and 10 m high in completely decomposed volcanic material. Grouted curtain was also formed behind, at the bottom …
An Analysis Of Causes Of Urban Landslides In Residual Lateritic Soil, Rajib Kumar Goswami, Baleshwar Singh
An Analysis Of Causes Of Urban Landslides In Residual Lateritic Soil, Rajib Kumar Goswami, Baleshwar Singh
International Conference on Case Histories in Geotechnical Engineering
Landslides in natural slopes of residual soil are a common problem encountered in tropical regions. Guwahati city, located in Assam in the north-eastern part of India, is an urban watershed covered by a number of hills and hillocks that are capped with lateritic soil. Although the slopes originally consisted of hard and strong rocks, their stability have been impaired by weathering, heavy rainfall and seepage flows. Encroachments and cuttings on the hill slopes due to unplanned urbanisation and earthquake tremors have aggravated the problem. A study of landslides was undertaken focussing on degree of weathering of the rock units, their …

Two recent failures of embankments that occurred in the year 2007 are taken into consideration for a detailed study. For each case, embankment failure mechanism, construction method used for the embankments, soil …
Analysis And Stabilization Of A Failed Cut Slope In Schist, S. B. Manolopoulou, T. T. Papaliangas, T. C. Dimopoulos
Analysis And Stabilization Of A Failed Cut Slope In Schist, S. B. Manolopoulou, T. T. Papaliangas, T. C. Dimopoulos
International Conference on Case Histories in Geotechnical Engineering
This paper focuses on the description, analysis and stabilization of a failed cut slope in schist. The slope is located near the top of a hill and was cut for the needs of a new industrial building. A few weeks after the excavation, a slide occurred along the schistosity plane of the slope. The slide was attributed to the effect of water which flooded the slope following an overflow of a water tank located a few meters above the slope crest. For the analysis both the deterministic and probabilistic approaches were carried out, with the input parameters determined from simple …
Analysis Of Dam Behaviour After Eighty Years Of Service, Paolo Croce, Giuseppe Modoni
Analysis Of Dam Behaviour After Eighty Years Of Service, Paolo Croce, Giuseppe Modoni
International Conference on Case Histories in Geotechnical Engineering
The paper reports on the behaviour of a masonry dam built in the Italian Alps in the early twenties of the last century and still in operation for electric power supply. The dam is 31 m high and its waterproofing is ensured by a multi-layered impervious facing, a concrete cut-off and a grout curtain protruding into the foundation soils. The geological location of the dam is rather complex, because its left abutment is located on a rock formation while the right one rests on a thick moraine deposit. Since its first impounding, large downstream water flows and significant movements of …

Analysis Of Problems In Cut Slope Survey And Design Based On Case Studies, Byung-Sik Chun, Chang-Koo Cho, Jin-Young Kong, Ju-Heon Lim, Jeong-Wan Lee
International Conference on Case Histories in Geotechnical Engineering
In construction of roads or large residential complexes, the formation of large scale cut slopes is inevitable due to the large proportion of mountains in Korea. The problems involving the slope stability has emerged as a major concern. Inaccurate subsurface exploration can result in slope failure during or after the construction, thereby increasing the construction cost and delaying the construction duration. This study reviews problems involving the cut slope survey methods, design criteria, and examining the collapse mechanisms through various case studies. This study suggests the optimum survey methods and design criteria based on the possible failure mechanisms.

International Conference on Case Histories in Geotechnical Engineering
In this study, two earth dams located in Malaysia were studied. The Labong Dam is a non-homogenous earth dam, whilst the Bukit Merah Dam is a homogenous earth dam. The performances of both dams against seepage were studied through the analyses of both observed and simulated phreatic surfaces. Simulations of seepage rate and phreatic surfaces through the dam were conducted by using SEEP/W model. The study showed that the SEEP/W model was able to predict (simulate) both the seepage rates and phreatic surfaces of the homogeneous and non-homogeneous earth dams with a reasonable accuracy. The Absolute Error (AE) between the …
Averted Piping Failure—Earth Dam On Permeable Foundation, Scott Newhouse
Averted Piping Failure—Earth Dam On Permeable Foundation, Scott Newhouse
International Conference on Case Histories in Geotechnical Engineering
“The dam builder has substantial control over the properties of the structure he builds, but he must take the foundation as it is furnished by nature.” (Cedergren, 1989) This paper presents the case of an earth dam built on a permeable foundation where seepage problems nearly caused failure of the dam. Early during first filling, before the lake was even half full, the dam showed significant seepage. Seepage boils appeared at the dam’s toe, indicating the onset of piping failure through the foundation. Although seepage boils indicating a failure mechanism appeared, dam failure was averted. The paper describes the events …

Back Analysis Of The Malakassa Landslide Using The Multi-Block Model, Constantine A. Stamatopoulos, Stavros G. Aneroussis
International Conference on Case Histories in Geotechnical Engineering
During the early hours of 18-02-1995 a landslide occurred at Malakasa, on the 36th kilometer of the highway joining Greece's main cities, Athens and Thessaloniki. The computed deformed geometry using this model agrees reasonably well with that measured. The back-estimated soil strength of 16o is in the range of the measured values (8-19o). Finally, state-of-the-art stability analyses, using the back-estimated residual soil strength, illustrated that the location of the slip surface can be predicted if it is assumed that only the saturated soil below the water table loses its strength.
