| Abstract: | Through introducing the comprehensive structure potential parameter of stress,the paper analyzes the structural characters of sandy clay.According to the samples of the sandy clay of the construction location of New Longyuan project II in Baoan district,Shenzhen,the paper made the confined compression tests in their intact,saturated and remoulded conditions to obtain the curves of the structural parameter,and inspected how the water content,dry density and pressure had an effect on the structural characters... |
