Through the shear test and the confined compression test, this paper studied the change rule of the shear strength of soil, cohesion, friction coefficient and confined compression test of void ratio, compression coefficient and compression modulus under the condition of same dry density and different moisture content. Results show that with the increase of moisture content, the shear strength linearly decreases, and cohesion and friction coefficient decreases, which can be expressed by logarithmic equation. Void ratio, compression coefficient and compression modulus changes significantly, but the sensitivity is different.
