御临河生态调节坝工程在导流明渠施工过程中,右侧边坡在连续降雨天气下,岩土体发生沿顺坡向结构面塌滑,使边坡贴坡挡墙发生变形破坏。根据对失稳边坡的定性和定量分析,结果表明,岩质边坡岩体中的结构面的产状、组合关系和结构面的抗剪强度,对岩质边坡稳定性起控制性作用。
In the process of diversion and open channel construction, the Yulong River ecological regulation dam project, the right side slope in the continuous rainfall weather, rock and soil occurred along the slope to the structural surface collapse, the slope slope retaining wall deformation and destruction. According to the qualitative and quantitative analysis of the unstable slope, the results show that the occurrence and combination of the structural plane and the shear strength of the structural plane in the rock mass slope rock body play a controlling role on the stability of the rock slope .
