Experiments and analysis on the effect of geosynthetics to prevent clogging in the gravel drain

Abstract

In the gravel drain method to prevent liquefaction, clogging of drain material is feared. In this study, the property of clogging of drain material and the effect of nonwoven geotextile to prevent clogging are discussed based on the laboratory test results. Additionally, an analysis method to predict pore pressure ratio, which is considerable the effect of clogging of drain material, is suggested.
