MITIGATION OF LIQUEFACTION SEISMIC RISK BY PRELOADING (2011)

The present paper deals with the use of numerical methods so as to assess the efficiency of an improvement method to reduce the liquefaction potential in a sandy soil profile subjected to shaking. The objective is to reveal the beneficial or unfavorable effects of preloading method on the soil response. This analysis shows the efficiency of the preloading in the mitigation of a liquefiable soil but the intervention at the foundation soil modifies the dynamic characteristics of the signal at surface.
