摘要
采用室内模型试验仿真构造了顺层和反倾斜块裂层状岩质边坡,分别定性地确定了可能出现的两种类型边坡的破坏模式,并根据实际工程中可能出现的边坡破坏特征,进一步拓展了这两种类型边坡的破坏模式,使其更具有普遍性.然后根据极限分析上限法基本原理,对室内模型试验结果进行分析求解,验证了极限分析上限法在该类型边坡稳定性分析中的适用性,并使极限分析上限法演绎到普遍破坏模式中.这进一步拓展了极限分析法的应用范围,为块裂层状岩质边坡稳定性分析提供了一种有效的分析手段.
The bedding and anti-dip block-layered rock slopes are modeled in detail by laboratory tests and the possible failure modes of two typical block-layered rock slopes are qualitatively determined.And the failure modes are extended to a general state based on the possible failure characteristics in practical engineering.In addition,the upper bound limit analysis method is adopted to analyze the results of the laboratory model tests and proves to be able to perfectly analyze the stability of a block-layered rock slope.A general failure mode of a block-layered rock slope is deducted,which develops the method to an effective approach for stability analysis of a block-layered rock slope.
