摘要：
The three-dimensional numerical analysis model was founded by FLAC3D program for slope, and different boundary conditions such as rough-rough boundary, rough-smooth boundary and smooth-smooth boundary were built in the model. The effect of boundary conditions on the factor of safety and slip surface of slope was studied. The results show that the safety factor of slope is the largest under the rough-rough boundary, the second under the rough-smooth boundary, and the smallest under the plane strain mode, which is closer to that of smooth-smooth boundary model. If the symmetrical homogeneous slope meets some conditions for the width-height ratio, the results from the rough-rough boundary and rough-smooth boundary are the same, which leads to the same safety factor and slip surface mode. © 2015, Central South University of Technology.
