Vibro Compaction Technique in Liquefaction Mitigation and Its Value Addition—A Case Study

Abstract

India being a rapidly developing nation requires quality infrastructural developments almost in every field ranging from industries, transportation, education, etc. Hence, the stability of these structures should be least ensured against the geotechnical concerns like bearing capacity, settlement, and liquefaction. The present study is about the development of an institutional campus located in seismically active zone. The proposed development comprises of both academic and residential buildings whose loading intensities ranges from single to maximum of 8 stories proposed to rest on open/pile foundations. The subsoil comprises of loose-to-medium dense sand (fines <12%) revealed that the soil is susceptible to liquefaction. The deep vibro compaction (VC) technique considered to be an effective solution to mitigate the liquefaction and found to be an alternate foundation solution over the conventional piling method. In addition, fully automated real-time quality control measures adopted to ensure the execution of VC works is also discussed.
