| 摘 要： | 顺层滑移-拉裂是顺层岩质边坡中常见的一种破坏模式,顺层滑动岩体范围大小是该类边坡稳定性分析及其加固支挡结构设计的基础,是设计人员最关心的问题。考虑边坡开挖卸荷效应对边坡岩体力学参数的影响,建立了顺层岩质边坡顺层滑动岩体范围的计算式,利用重庆至怀化铁路沿线顺层岩质路堑边坡失稳破坏的调查资料进行对比分析,结果吻合较好。

| Abstract: | Bedding slipping and fracturing is one of failure modes of consequent rock slope.The extent of bedding slipping rock mass is the basis of stability analysis and structural support design of consequent rock slope.Therefore,it has become one of the most important problem to which many engineers regarding slope engineering pay attention.By considering the reduction of shear strength of the bedding plane due to unloading and weathering,and the limit equilibrium state of the unstable rock mass,formulas used to calculate the extend of bedding slipping rock mass of consequent rock slope is deduced.The comparison between the calculated and observed data of a consequent rock slope in railway from Chongqing to Huaihua was carried out.It shows that the results are coincident.The formulas could be used in the structural support design of consequent rock slope. |
