An Overview of Liquefaction Mitigation Countermeasures

Abstract

The liquefaction problem and its consequences have been the major issues that have attracted the attention of the public as well as government bodies for a few decades. Bihar state belongs to the severe to extremely vulnerable seismic zones of India. Therefore, the consequential damages due to soil liquefaction are on a large scale. It is impractical and extremely difficult to prevent soil liquefaction if the susceptible zone extends to a greater depth. This paper reviewed the commonly used traditional and research trends of liquefaction mitigation countermeasures. Although traditional methods are widely used in engineering practice, the problems associated with pollution, cost, and disturbance to existing structures have become a great challenge. With continuous, progressive, and multidisciplinary research, new methods have been developed that solve all three concerns: social, economic, and environmental. The research trend is to develop methods based on the principles of passive site remediation, induced partial saturation, and microbial geotechnology.
