摘要
本文以华茂石场现状开采边坡为研究对象。对其工程水文地质条件和边坡开采现状进行分析,确定安全系数,开展定性定量综合分析。理正软件确定剖面后,使用赤平投影法对最不利剖面分析后,结合flac 3D进行有限元模拟计算,结果表明,该剖面整体安全系数1.30,边坡整体在自重+地下水、自重+地下水+爆破及自重+地下水+地震工况下,均处于稳定状态。并提出相应的治理和监测建议,为类似的大型露天花岗岩边坡稳定评价和治理监测提供相关经验。
In this article,the engineering hydrogeological conditions and slope mining status of Huamao Quarry were analyzed to determine the safety factor and carry out qualitative and quantitative comprehensive analyses.The Lizheng software was used to determine the profile,and after using the stereographic projection method to analyze the least safe profile,finite element simulation calculations were carried out in conjunction with Flac 3D.The results show that the overall safety factor of the profile is 1.30,and the slope is in a stable state under self-weight+groundwater,self-weight+groundwater+blastingand self-weight+groundwater+earthquake affairs.Based on the above,corresponding governance and monitoring suggestions are proposed to provide relevant experience for the stability evaluation and governance monitoring of similar large-scale open-pit granite slopes.
