基岩地区某建筑高边坡稳定性评价

本文以天津市蓟县基岩区二元结构建筑高边坡为例，针对该边坡岩体结构特征以及坡顶填土区变形破坏迹象，判断出边坡可能破坏模式，在此基础上，通过现行规范推荐的圆弧滑动法和平面滑动法，对边坡在各种工况条件下的稳定性状况进行了评价，并提出了采用挡墙、锚杆以及植被网等相应治理措施建议，为天津蓟县基岩区土石二元结构建筑高边坡的稳定性分析与治理提出了一种新的思路和方法。

The paper based on case of two dimensions structure high slope in basement rock zone, Jixian, Tianjing City. It presented the type of unstable-slope by investigating the characteristics of the slope rock type as well as the structures deformation signs on the top of the slope filling zone. It also gave an evaluation on the slope stabilities under all types of site conditions by referring the two standard calculations- the cambered surface slip method and the plane surface slip method from engineering specification. In the end, it provided the remediation suggestions by building anti-slope walls, anchor cables or plants net. All these methods are considered as the new ideas of the slope stability analysis on two dimensions structure high slope in basement rock zone, Jixian, Tianjing City.
