Physical and mechanical properties of soft clay distributed at Thilawa area along Yangon river based on soil investigation results carried out under JGS standard

Abstract

In this papers, soil laboratory test results are shown which are obtained from samples taken with a sampling method prescribed in JGS (Japanese Geotechnical Society) Standard, at Thilawa Area along Yangon River. Physical and mechanical properties of Thilawa soft clay are identified and compared with ones of soft clay in Japan and also with existing research results in other countries. As a result, it is identified that the quality of sampler affects the result of unconfined compression test of Thilawa soft clay, friction angle of Thilawa soft clay under effective stress are smaller than ones of soft clay in Japan, and also coefficient of consolidation is smaller with 1/6 to 1/3 times of soft clays in Japan.
