Liquefaction for an unsaturated soil with suctions control

Abstract

This study conducts out unsaturated, compacted soil that aims to appear the axial strain properties under cyclic loading.The cyclic triaxial apparatus and relative humidity air circulation system in order to control high suction are employed.Test programs consist of two series, and Series 1 investigatesthe influence of compaction water content on deformation properties. Other hands, establishing suction and lateral confining pressure are key features in Series 2. The obtained summary is appeared as follows. Unsaturated, compacted soil have verification that smoothly axial deformations are interpreted, and compression deformations are occupied through the cyclic loading. Comparing axial strain properties with/without applying high suction, the specimens with high suction seem to be easy occurrence compression large deformations.
