摘要
通过对金川水电站右岸导流洞出水口边坡的岩性、构造、可能存在的破坏机制和岩体物理力学性质的研究,利用计算辅助软件建立三维地质模型,分析该边坡的结构面组合形式,确定由这些结构面切割而成的块体的空间位置,并利用商用岩石边坡楔形体稳定性分析软件Swedge对各潜在不稳定块体进行计算。计算结果表明,各种工况下的边坡均具有很好的稳定性。
The lithology,structure,physical and mechanical properties of rock mass and possible failure mechanism of the slope at the outlet of the diversion tunnel at the right bank,Jinchuan Hydropower Station were studied.A three-dimensional geological model was established by using computer aided software.The combination modes of the structure plane for the slope were analyzed, and then the locations of blocks cut by the structural planes were determined.The stability of potentially unstable blocks was calculated by means of the Swedge software,business analysis software for the stability of rock slope wedges.The calculated results show that the slope is stable under various working conditions.
