水平凸型边坡破坏分析

本文根据水平凸型边坡的破坏机理,建立了一套适用于计算水平凸型边坡稳定性的三维极限平衡方法,并用这一方法对水平凸型边坡的稳定性进行了研究。当相对曲率半径R_2/H≥3时,曲率对边坡的稳定性影响很小,曲率影响边坡稳定性的主要原因在于曲率不同时,其边坡体内周向应力的差异。

The Failure Analysis of Horizontal Convex Earth Slopes

According to the failure mechanism of horizontal convex slopes, this paper proposed a three-dimensional limit equilibrium method which is adapted for calculating the stability of the slopes. It is showed that the curvature of the convex slope has less effect on the stability of the slope while the relative radius of curvature (R2/ H) is larger than or equal to three. The main reason that the stability is affected by curvature is that the peripheral stresses are different when the curvature of the slopes are different.
