链子崖危岩体稳定性分析及锚固工程优化设计

Stability analysis and optimal anchoring design on Lianziya dangerous rockmass

摘要: 链子崖危岩体防治工程包括对其关键块体———水马门危岩体采用预应力锚索加固 ,对危岩体下伏煤层采空区进行钢筋砼承重阻滑键加固以提高T8～T1 2 缝围限的 2 50万m3危岩体的稳定性 ,对危岩体上覆的雷劈石古滑坡体进行地表排水以提高其稳定性 ,在危岩体东侧猴子岭崩滑堆积体上修砌浆砌块石防冲拦石坝以减缓T1 ～T7缝危岩体直接冲入长江 ,重点介绍预应力锚固工程情况

Abstract: Comprehensive measures to control the rockmass is applied, including pre stressed cable anchoring,reinforced concret filling, surface drainage, and defensive dam. Pre stressed anchoring, an major engineering measure for the Lianziya dangerous rockmass, is discussed in detail.
