Evaluating the efficiency of stone columns in mitigating liquefaction risks and enhancing soil bearing capacity: A case study

Several processes allow the improvement of soils such as vibrocompaction, stony columns, static horizontal compaction etc. These reduce risk liquefaction potential and making it possible to build on this type soil when space restriction require it. Stone columns are a recognized method improvement, which consists creating large diameter using special vibrators with granular filling materials introduced into ground. The objective work is evaluate effectiveness stone made in seismic zone containing liquefiable materials, regards reduction bearing capacity soil. approach followed exploitation geotechnical investigation tests (CPT Cone Penetration Test), (SPT: Test, (pressuremeter tests), carried out before after treatment. This study showed that network gravelled produces an enhanced effect by improving modulus elasticity reducing settlement process allows for characteristics its soils, infrastructure development projects area.
