开采扰动下的边坡稳定性问题一直是岩土工程中的一个重要研究内容,以某矿Ⅳ-Ⅳ剖面为研究对象,在极限平衡理论的基础上,借助GEO-SLOPE软件,对开采扰动后的边坡现状稳定性进行计算分析,结果表明边坡目前处于不稳定状态。为了提高边坡稳定性,对上部采取局部削坡减载的治理方案,并采用极限平衡方法,分别考虑岩体折减和松散体2种情况进行稳定性分析。分析结果表明,2种情况下的边坡均处于稳定状态,从而达到治理的目的。
The slope stability problem under mining disturbance has been an important research topic in geotechnical engineering. Taking a Ⅳ-Ⅳ section of a mine as the research object, on the basis of the theory of limit equilibrium, with GEO-SLOPE software, The current status of slope stability calculation, analysis shows that the slope is currently in an unstable state. In order to improve the stability of the slope, a control plan of partial slope reduction and load reduction is adopted to the upper part, and the stability analysis of two cases of rock mass reduction and loose body is carried out by using the limit equilibrium method. The analysis results show that the slope in both cases are in a stable state, so as to achieve the purpose of governance.
