| The structural surface affects the stability of rock slope, and the transfixion property of structural surface is the key to study the structural surface. In view of a rock slope project, using the software of Slide limit equilibrium method, the influence of the transfixion property on the stability of the rock slope is studied from the inclination angle of the structural surface, the transfixion rate and the transfixion form. The calculation results show that the form of structural plane penetration has no obvious influence on slope stability. When the slope is in a stable state, the greater the inclination angle of the structural surface is, the greater the safety factor of the slope is. When the slope is in a state of instability, the greater the inclination angle of the structural surface is, the smaller the safety factor of the slope is. When the inclination angle and transfixion form of the structural surface are certain, the greater the transfixion rate of the structural surface is, the smaller the safety factor of the slope is, and the slope is prone to instability and failure. |
