本文根据现场观测、试验以及工程地质和岩石力学理论,进行了建立在研究岩体结构效应基础上的陡崖岩体崩塌的物理及力学过程的调查研究,分析了不同因素产生的岩体不稳定性,建议了岩体崩塌的四个阶段和三种类型,定量演算了岩体边坡的稳定性并用力学判据进行预报。到目前为止,滑动理论通常用来计算陡崖岩体的稳定性问题,但在边坡破坏机理不同于滑坡时不宜采用,为此提出了岩石力学的新概念和方法,它们将在岩体工程和岩石力学理论上起到重要作用。
Based on the field observation, experiment, engineering geology and rock mechanics theory, this paper investigates the physical and mechanical processes of the steep rock mass collapse based on the study of the rock mass structure effect, and analyzes the rock mass instability caused by different factors We suggest four stages and three types of rock mass collapse, and calculate the stability of rock slope quantitatively and predict it with mechanical criterion. So far, the sliding theory is usually used to calculate the stability of steep rock mass. However, it is not suitable for the failure mechanism of slopes to be different from landslide. Therefore, new concepts and methods of rock mechanics are proposed. They will be used in rock mass engineering And rock mechanics theory plays an important role.
