...Semko Arefpanah; Alireza Sharafi Stone column technology is a method used to reduce liquefaction in saturated sediments. By using materials with greater permeability than the surrounding soil, stone columns can help drain excess pore water pressure and mitigate liquefaction potential during seismic...

... of a sufficient size can be created economically in sand deposits, which would be expected to contribute to improving ground conditions as a countermeasure against soil liquefaction. Four different tests are carried out under different grouting conditions, where grouting is conducted with and without forcible...

...S. P. Gopal Madabhushi Soil liquefaction continues to be a major source of damage to buildings and infrastructure after major earthquake events. Ground improvement methods are widely used at many sites worldwide as a way of mitigating liquefaction damage. The relative success of these ground...

.... The risk of liquefaction at the Caspian Sea Republics Oil Swap (CROS) project site for loose saturated sandy layers down to 13 m was revealed subsequent to completion of the geotechnical investigations. Following a detailed study, dynamic compaction was selected to be the best option, especially...

...P. A. L. F. Coelho; S. K. Haigh; S. P. Gopal Madabhushi; T. S. O'brien In situ densification is a popular technique to protect shallow foundations from the effects of earthquakeinduced liquefaction, current design being based on semiempirical rules. Poor understanding of the mechanisms governing...

...A. Sadrekarimi; A. Ghalandarzadeh Liquefaction induced by earthquakes can cause major destruction to foundations and buildings, mainly as a result of excess pore water pressure generation and softening of the subsoil. Several remediation methods are performed that reduce the excess pore pressure...

...R. Bouferra; I. Shahrour This paper concerns a study of the influence of fines on the resistance to liquefaction of a clayey sand. The study is carried out using a triaxial apparatus on a reconstituted sand-clay mixture containing a low fraction of clay. After a description of the soil used...

...J. Blewett; P. K. Woodward Vibro-replacement is a cost-effective method of stabilising liquefiable soils. The exact mechanisms by which vibro-columns can mitigate liquefaction are complex and difficult to verify in the field. A novel low-cost, seismic frequency triaxial testing system is presented...

... approach proposed by Seed and Booker to describe the main mechanisms of pore pressure dissipation. Modifications to this analysis are proposed, in view of the laboratory results, to include aspects of liquefaction mitigation due to the rigidity of the columnar inclusion and the performance constraints...
