Micropiled-Raft Foundations For High-Rise Buildings On Soft Soils — A Case Study: Kerman, Iran, Hessam Yazdani, Mehdi Momeni, Kianoosh Hatami

International Conference on Case Histories in Geotechnical Engineering

For the structures supported on soft soils, piled raft foundations have been shown to be more economical than conventional piled foundations. In piled raft foundations, the bearing capacity of the underlying soil is taken into account to support the superstructure loads and the piles are placed such that they increase the bearing capacity of the raft and control both the total and differential settlements of the superstructure. In the city of Kerman, Iran, the predominance of soft soils had historically hampered the construction of high-rise buildings across the city. Recently, an eighteen-story reinforced concrete building was constructed on a micropiled-raft ...

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 ...

International Conference on Case Histories in Geotechnical Engineering

The floors and non load bearing walls of a house, having expansive black cotton soil underneath, have been repaired by two methods. A part of the damaged house floors and walls were repaired by the conventional method i.e. removing the expansive soil completely and replacing with non expansive granular material. The remaining part was repaired by integrated approach as described later by Jain and Mewade (2010). The Jain and Mewade (2010) approach consists of removing the expansive soil underneath the damaged floor by about 0.5m, making 50mm diameter, 1m deep holes at 0.75m centre to centre and ...


Response Of Piled Raft Foundation On Soft Clay Under Seismic Load, Alireza Saeedi Azizkandi, Tara Maali, Mohammad Hassan Baziar Apr 2013

Response Of Piled Raft Foundation On Soft Clay Under Seismic Load, Alireza Saeedi Azizkandi, Tara Maali, Mohammad Hassan Baziar

International Conference on Case Histories in Geotechnical Engineering

A number of researchers has extensively investigated the vertical load bearing mechanism of piled raft foundation, by applying elasticity theory and finite element method. The study on the load bearing mechanism under horizontal loading or during earthquakes, however, is very limited. This is partially because piled raft foundations are considered as raft foundations in the current design practice. Since the behavior of a piled raft foundation during earthquakes is considered fairly complex due to dynamic interaction among a raft, piles and a soil, the design procedure should include the effect of this mechanism in an appropriate manner. In other hands ...

An oil storage tank at the North suburb La Goulette (Tunisia) was founded on reinforced soft soil by floating sand columns of 6 m in length and 11% of improvement area ratio within a thick compressible clayey soil. Serious contamination of tank due to very significant differential settlement forces the decision to terminate its operations. Reinforcement by inclined rigid inclusions was suggested to neutralize the evolution of consolidation settlement in sub compressible clay layers. Numerical predictions were implemented for the study of the post behavior of tank on reinforced soil by rigid inclusions. Effectiveness of solution using inclined rigid inclusions ...


The Effect Of Quality Of Subsoil Structure Identification On The Execution Of Pile Structures For Bridge Supports, Maciej Kumor, Zbigniew Młynarek Apr 2013

The Effect Of Quality Of Subsoil Structure Identification On The Execution Of Pile Structures For Bridge Supports, Maciej Kumor, Zbigniew Młynarek

International Conference on Case Histories in Geotechnical Engineering

Supports of road viaducts or bridges are founded predominantly on piles. This is determined by the subsoil structure and the location of the designed object. In certain cases the selection of the pile system is also influenced by the neighboring buildings and infrastructure. The design for bridge foundation in such cases needs to be based on high quality geotechnical documentation. Although this criterion is specified in Eurocode 7: PN-EN 1997 parts 1 and 2, binding throughout Europe, including Poland, frequently geotechnical documentations are not very precise and do not present an accurate subsoil structure, leading to building disasters. Such a ...
