摘要
该文通过对老挝某金矿的工程地质、水文地质条件进行调查,分析了其地层分布、地质构造和岩土体特性,并确定了各地层的岩土力学参数。应用Geo-slope软件计算了选矿场地各边坡在天然工况、持续降雨的饱和工况和地震工况下的稳定性系数,认为整体边坡处于稳定状态;对典型边坡进行了分析,认为部分分台边坡处于不稳定状态,且受持续性降雨的影响最大,地震次之。在稳定性分析与评价后,对边坡提出了相对应的防治措施。
In this paper,through investigating the geological and hydrogeological conditions of a gold mine in Laos,the distribution of strata,geological structure and characteristics of rock and soil are analyzed,and the rock and soil mechanical parameters of each stratum are determined. The Geo-slope software is used to calculate the stability coefficient of the slope under the natural condition,the saturated condition of continuous rainfall and the earthquake condition. It considers that the whole slope is in a stable state. The typical slope is analyzed,and it considers that the partial slope is in the unstable state,and the influence by sustained rainfall is the greatest,the earthquake is second. After the analysis and evaluation of stability,the corresponding prevention and control measures are put forward.
