摘要
边坡支护结构由于受到侧向岩石压力而产生变形,其本质就是边坡稳定性问题,侧向岩石压力的计算对工程设计尤为重要。该文结合现行国标《建筑边坡工程技术规范》(GB50330-2013),阐述了主动岩石压力产生机理,整理得出岩质边坡主动岩石压力的理论计算法和经验计算法,确定了破裂角的选取原则及等效内摩擦角的计算方法。
The deformation of slope supporting structure is caused by lateral rock pressure, the essentially problem is slope stability. The calculation of lateral rock pressure is particularly important for engineering design. Combined with the current national standard Technical Code for Building Slope Engineering(GB 50330-2013), this paper expounds the generation mechanism of active rock pressure.The theoretical calculation method and empirical calculation method of active rock pressure of rock slope are obtained, and the selection principle of fracture angle and the calculation method of equivalent internal friction angle are determined.
