AB  - The cohesion c and friction angle I are the shear strength parameters influencing the stability of slope. Any of them changes, the factor of safety of slope will change, many work has been done on the relationship between shear strength parameters and factor of safety, but it has seldom been considered in the literature how the slip surface changes at the same time. In the present paper, the strength reduction method is used to find out the effect of shear strength parameters c and Phi to the distribution of slip surface. The study shows that, the slip surface is affected by the function of c and Phi instead of the separated one, the function is I>=c/(Gama tan Phi). If I> is a constant, the slip surfaces remain the same even the shear strength parameters changes. Increasing of I> leads to the slip surface moving far away from the slope surface. Decreasing of I> lead to the slip surface comes closer to the slope surface.
