摘要
In this paper, there are two different color（red and yellow）soils from the slide zones as two samplers to be studied through libratory test. Firstly, the basic physical and mechanical properties about two soils were measured. Then the red soil which was poorer in shear strength was selected as an interlayer, through changing thickness of interlayer and its water content, based on orthogonal design, using triaxial shear tests, the shear strength（internal friction angle φ and cohesion c）of the landslide mass were studied. The results show that among factors the water content of interlayer soil is the greatest influence to the shear strength of landslide soil, then interlayer thickness also has a certain effect.
