Abstract
India has seen a substantial growth in various Soil Improvement Techniques over last decade. A particular technique has been chosen based on Project location, Sub soil profile, Technical requirements, Time available and allowed budget for foundation. An expansion was planned for a leading fertilizer plant in North India. Project was located in high seismic zone having PGA of 0.24g. The site was underlain by liquefiable loose fine sands up to depth of 10m to 12m. Existing plant structures were built on Stone Columns few years back. This paper presents a case study where Vibro-compaction technique was successfully used to mitigate liquefaction and to increase bearing capacity. It also outlines the detailed geotechnical investigation carried out using standard penetration test (SPTs) and Electric Cone Penetration Test (ECPTs) to confirm the soil improvement in the treatment area. In addition, radial effect of Vibrocompaction outside the treatment area is also studied and reported.
