In this paper, the changing law of the peak and residual cohesive force and internal friction angle for undisturbed soil from three different sampling sites in Bijie area were obtained through the indoor experiment. In the case of natural undisturbed water content, the peak and residual cohesive force decrease with the exponential relationship of water content, while the peak and residual internal friction Angle decrease linearly with the water content range. Based on the traditional Culon-morper shear strength criterion the changes of peak and residual shear strength with water content were obtained. The research in this paper is helpful to understand the change of shear strength with water content in Bijie area and to guide engineering practice.
