［摘要］以某矿场的山体边坡支护为背景，对支护后的边坡进行了现场检测，没有出现破坏迹象。卸载后，残余变形微小，P-s曲线没有出现拐点。结果表明,变形及抗拔力满足设计要求。同时进行了数值模拟，发现在支护后边坡的位移比支护前变小，坡体的应力值增大，支护有效的控制了坡体的变形。各杆件的轴力在支护过程中变化也趋于合理，与设计计算基本吻合，与现场测试的变形曲线基本一致。说明锚杆在边坡支护工程中有很广泛的应用前景。

Abstract: This paper studied the mechanism of anchor on the basis of a slope in a Mine. In-site tests had been taken after the slope support finished. No damage had been found. Residual deformation was very small after unload and no inflection point had been found in the P-s curve. The results show that the deformation and pulling capacity meet the design requirements. The numerical simulation was carried out. The simulation results show that the displacement of the slope is smaller and the stress is lager than before supporting. The slope deformation is well controlled after supported. The axial force change is reasonable in the supporting process. The simulation results meet the design calculation and in-site test curves. The anchor support has a very broad application prospects in slope supporting engineering.
