摘要
岩质边坡工程中经常会遇到层理和节理极为发育、岩体被切割成许多离散块体的块裂层状岩体边坡,该类型边坡的破坏模式和稳定性影响因素有别于一般的岩质边坡。针对该类边坡,通过室内模型试验,探讨不同开挖坡度和层理面倾角下岩质边坡的破坏特征,并运用Sarma法对于室内模型试验结果进行分析,计算结果表明Sarma法适用于块裂层状岩质边坡的稳定性分析,这对该类岩质边坡的工程实施具有一定的指导意义。
In rock slope engineering,the block-layered rock slope may be frequently met.This kind of slope contains quite a number of beddings and joints.And the rock mass is separated into several discrete blocks.The failure mode and stability-affecting factors of this kind of slope are quite different from other kinds of slopes.Through indoor model tests,a study on the stability of the slope with different slope angles and different bedding angles was conducted.The Sarma method is adopted to evaluate the stability of the slope. The analysis results are quite consistent with those from indoor model tests. This study can be a good guide for the block -layered rock slope in engineering.
