In view of the current problems such as less research on the combined support of anchor cable and frame lattice beam in slope reinforcement, the actual project of slope support on the left bank of a hydropower station was taken as the background. The stability of the original slope was analyzed by combining the limit equilibrium method and the finite element strength reduction method. The combined support scheme of anchor cables and frame lattice beams was studied. It mainly included anchor cable anchoring force calculation, anchor cable arrangement spacing, anchor cable length, optimal incidence anchoring angle and frame lattice beam size, etc. Finally, the support effect was studied by combining with numerical simulation. The results show that the original slope needs to be reinforced and supported. The error of the original slope safety coefficient obtained by the finite element strength reduction method is less than 1.5%-2.0% with the limit equilibrium method. The temperature loading method was used to simulate anchor cable prestressing for stability analysis of slope with combined support of anchor cable and frame lattice beams, and the combined support is effective and no obvious slip crack surface appears after the support. The study can provide reference for similar slope support projects.

针对目前锚索框格梁联合支护在边坡加固中的研究较少等问题，以某水电站左岸边坡支护实际工程为例，结合极限平衡方法和有限元强度折减法分析了原始边坡稳定性，研究了锚索框格梁联合支护方案（包括锚索锚固力计算、锚索布置间距、锚索长度、最优入射锚固角度及框格梁尺寸等），并结合数值模拟对支护效果进行了研究。结果表明，原始边坡需进行强化支护，有限元强度折减法计算原始边坡安全系数较理论分析方法误差在1.5%~2.0%范围内；使用温度荷载方法模拟锚索预应力对锚索框格梁联合支护的边坡进行稳定性分析，联合支护效果显著，支护后无明显滑裂面出现，研究结果可为类似边坡支护工程提供参考。
