摘　　要：根据结构面倾角与露天矿不同边帮边坡角之间的关系,对倾斜层状岩质边坡进行分类,在此基础上提出层状边坡一般加固技术。针对预应力锚杆加固技术,推导出锚杆最优安装角度的计算公式,通过工程实例计算验证了公式的可靠性,研究结果为锚杆支护边坡的安装设计及优化提供了理论支持。The inclined bedded rocky slopes were classified based on the relationships between the inclination of structural surface and the slope angle of different sides in open pit mines and the general reinforcement technology for layered slopes was proposed.A calculation formula of the bolt’s optimal installation angle was derived for the pre-stressed bolt reinforcement technology.Reliability of the formula was verified by engineering projects.The research results provided a theoretical support for design and optimization of the bolt support slope installation.
