紧邻建筑物山体岩质顺向高边坡稳定性评价及治理方法研究
摘要:分析了目前岩质高边坡的特点及治理中遇到的困局,总结了定量评价岩质高边坡稳定性方法的优缺点,以某工程紧邻建筑物山体边坡为实例,采用强度折减法对边坡整体稳定性进行了评价,并研究了该山体岩质顺向高边坡的破坏机理和形式,因地制宜,坡顶支护结构选择了新型GSS2A主动防护网系统,坡底选择了护脚墙和圆拱形骨架圬工结构。实践证明,边坡支护设计中整体稳定性评价方法恰当,支护结构安全、经济、美观,便于施工,为类似边坡治理提供了借鉴。
Abstract:The paper analyzed the current characteristics of high rock slope and the predicament in treatment, summarized the advantages and disadvantanges of the quantitative evaluation of high rock slope stability. Taking a project next to the building of mountain slope as an example,it used strength reduction method to evaluate the slope stability, and studied the failure mechanism and form of mountain rock bedding high slope. With adaptation to local condition, the top of slope supporting structure selected the new GSS2 A active protection net system, the bottom of slope selected the foot wall and the arched frame masonry structure. The practice shows that the overall stability evaluation methods is suitable in the design of slope supporting, and the supporting structure is safe,economical and beautiful, convenient for construction. It provides reference for the similar slope treatment.
