| 摘 要： | 基于地震波通过结构面时的反射折射理论,探讨位移反射系数与地震波入射角的关系,建立一定条件下边坡稳定性的地震波入射角判据;同时认为,当前常用的莫尔强度准则不适合作为地震荷载作用下岩体破坏的判断依据,并针对地震荷载对莫尔强度准则进行修正. |

| Abstract: | Based on the refraction and reflection theory of seismic wave through the weak interface, the relation between reflection coefficient and incident angle of earthquake wave is discussed; and the instability criterion of slope affected by incident angle of seismic wave under certain conditions is put forward. It is pointed out that Mohr＇s strength criterion is not suitable for failure criterion of rocks under seismic loading; and the modification of Mohr＇s strength criterion is proposed according to the mechanical properties of seismic loadings. |
