Soil Liquefaction Evaluation using Deterministic and Probabilistic Approaches: A case study

Abstract

A study has been undertaken to provide a better understanding of the liquefaction potential evaluation. This paper discusses the evaluation of seismically induced Liquefaction based on semiempirical field-based procedures using the Standard Penetration Test (SPT) profile of soil. This work has been carried out to initiate such studies in the region and to address the problem of seismically induced liquefaction based on deterministic as well as probabilistic approach. A case study for IIT Guwahati with 3 different borehole locations has been carried out for 3 different Earthquake Moment Magnitude of M=5, 6 and 7 respectively. Liquefaction would be suspected to occur upto a depth of 15-18 m. The results obtained in probabilistic approach are in good agreement with deterministic approach. This Study provides a good understanding to account for the liquefaction assessment based on two approaches.
