为了评价露天西边坡的稳定性,进行了大量的室内与现场岩石力学试验,主要有岩体和岩体结构面的抗剪强度、岩体弹性模数、岩体应力与应变等试验。综合分析试验结果表明,黑色破碎岩体和软弱结构面是决定西边坡稳定性的主要因素;而处于黑色破碎岩体中的硅质白云岩相对来说完整性较好,它对围岩及边坡稳定性能起一定的控制作用。
In order to evaluate the stability of open slopes in the west, a large number of indoor and field tests on rock mechanics have been carried out. The tests mainly include shear strength of rock mass and rock mass, elastic modulus of rock mass, stress and strain of rock mass. Comprehensive analysis of the test results show that the black crushed rock mass and weak structural plane are the main factors that determine the stability of the western slope; while the siliceous dolomite in black crushed rock is relatively complete, Slope stability plays a certain role in the control.
