Abstract

Abstract

The research on shear strength of unsaturated soil is important in soil mechanics research. The shear strength of soil depends on the difference of water content. Based on the object of remolded soil in Yunnan province and the means of the direct-shear tests, the author surveyed the shear strength parameter of soil with different water content.According to the test results, the shear strength of soil don't decreased monotonously with the increasing of water content, interest of a parabola with up and down,which is some positive significance to know the relationship of between soil strength and water content.
- unsaturated remolded soil,
- shear strength,
