| 摘 要： | 依托某楔形体滑坡工程，基于FLAC3D开展路堑边坡楔形体破坏机理数值模拟研究。结果表明:边坡后缘主要是受拉张破坏，前缘和侧滑面主要受剪切破坏，底滑面和侧滑面为边坡抗滑的主要结构面，侧滑面的主要作用是切割岩体使之成为独立的块体，具备产生楔形体滑动的必要条件，主滑面的连通性和强度是楔形体边坡稳定性的制约因素。

| Abstract: | Relying on the prevention project for slope collapse of a secondary school in Zhuhai, the stress strain of prestressed steel wire rope strengthened by rock mass is monitored and analyzed. By selecting four typical dangerous rock masses to monitoring of wire rope stress, the variation rule of wire rope stress in the cracking process of dangerous rock mass layer by layer is obtained and the working state of anchor wire rope in the cracking process of dangerous rock mass layer by layer is analyzed. It is of great significance to ensure that the dangerous rock mass is in a stable state during the construction process and eliminate the hidden danger in the construction process. |
