为了保证岩质边坡和坡顶输电铁塔的稳定性，采用边坡稳定理论分析法对该岩质边坡进行稳定性分析，确定边坡可能破坏模式为沿外倾结构面交线滑移及局部掉块。采用摩尔-库仑等面积圆 D- P 屈服准则来代替传统摩尔-库仑准则，经计算表明与摩尔-库仑准则十分接近。选取合理的岩土体物理力学参数，运用大型有限元软件 Midas/GTS 对桩锚挡墙和板肋式锚杆挡墙两种设计支护方案进行对比计算分析，计算表明桩锚挡墙支护方案优于板肋式挡墙，采用桩锚挡墙的优选支护方案。通过对比现场监测结果，验证了桩锚挡墙支护体系的可靠性，指导桩锚挡墙的信息化施工，为类似工程边坡支护方案设计提供参考。

In order to ensure the stability of rock slope and transmission tower ,the stability of the rock slope is analyzed by applying the slope stability theory analysis method ,and the failure modes of the slope are defined to be the intersect-ing-line slipping and local rock-chunk dropping along extravertion structure plane .By selecting Mer-Kulun D-P yield cri-terion and reasonable physical parameters of rock soil ,the finite element software Midas/GTS is used to analyze the two design schemes as the pile-anchor retaining wall and plate-ribbed retaining wall with anchors .The results show that the pile-anchor retaining wall is better than plate-ribbed retaining wall ,and the reliability of the pile-anchor retaining wall is verified by field comparison and monitor ,which could provide some references for the design of similar projects .
