山体超高岩质边坡治理实例分析

以某厂山体超高边坡为研究对象,详细介绍了该边坡的设计及治理措施。首先根据边坡的地质特点及原始坡率进行边坡坡型的初始设计,之后按照动态设计、信息化施工原则对设计坡型进行优化调整。根据区域地质构造、水文资料和地震情况,定性地判断边坡破坏的趋势和范围;在此基础上,选取有针对性的计算模式进行定量分析,确定边坡的稳定性安全系数并完成其稳定性评价。还介绍了边坡排水系统设计、支护结构设计及支护施工中出现的问题及相应的处理措施。该边坡的安全性评价方法和治理措施对类似超高岩质边坡的处理具有重要的参考价值。

Case History of Treatment of An Extra-high Rock Slope

A case history of design and treatment of an extra-high rock slope is presented in this paper, as example. The preliminary design was carried out based on the geological characteristics and the initial ratio of slope. Optimization and modifications were made subsequently on the basis of dynamic design and information-oriented construction. Qualitative analysis of the failure tendency and the failure range of the slope were carried out according to the regional geological structures, hydrological and seismic conditions. Quantitative analysis was carried out and the slope stability was analyzed using FEM and LEM methods. The design of the drainage system, the design of the anchor-plate retaining system and the countermeasures of many problems in the constructions of the slope were also discussed in this paper. Both the safety evaluation method and the treatment of the slope are valuable to treatment of other similar extra-high rock slopes.
