云南楚大公路膨胀土的土性试验研究

Experimental research on properties of expansive soil on Chu-da expressway in Yunnan

对楚大公路滑坡膨胀土进行了较全面的土性试验 ,分析并提出了膨胀土在变形过程中的形变模量新指标 ,获得了直接用膨胀土填筑路堤。

A variety of experiments for determining the properties of the landslide expansive soil in Chu da expressway are conducted.A new index on modulus of deformation which used for the deformating phase of expansive soil is analysed and put forward in this paper,and the necessary parameters for constructing the embankment with natural expansive soil and setting up the design fomula of reinforced slope are presented.
