摘　　要：结合某软岩高边坡工程 ,对土钉支护结构的受力和位移进行了监测。通过对实验数据分析了土钉支护的结构原理和受力状态 ,表明土钉支护工作原理既不同于锚杆结构 ,又不同于土钉墙。同时根据施工过程中对边坡水平位移的监测 ,及时调整了边坡的支护参数、开挖深度和支护时间 ,控制了施工过程中边坡的变形 。The monitoring results of the forces applied on a soil-nailing support structure in a high slope project with weak rock and relative displacements are presented in this paper. The analysis of the monitoring data reveals that the working principle of soil-nailing support is different from not only an anchor structure, but also a soil-nailing wall. According to the monitoring results of the horizontal displacement in the slope during the project construction, the supporting parameters, cutting depth and supporting time for the slope were adjusted so that the high slope was kept stable on the whole.
