摘　　要：露天边坡的稳定性关乎到采场工作人员的生命安全以及采场工作效率。在采场选取三个典型边坡情况,利用理正计算软件,以云南某露天采石场为研究背景,结合理正软件岩质边坡分析功能,综合考虑自然、地下水与爆破地震震动因素,对不同荷载组合下的边坡稳定性进行计算和分析,结果表明,在三种荷载组合下D-D′、E-E′剖面边坡稳定性安全系数满足规范,而F-F′剖面会失稳破坏,需要进行一定的防护措施。Stability of side slope is vital to safety of staff lives and stope productivity.Three typical situations of side slope in opencast quarry was selected and Lizhen calculation software was utilized to got the following results:one opencast quarry of one Yunnan open pit mine was taken as the study background,combining with the side slope analysis function for rock side slope of Lizhen software,with the comprehensive consideration of nature,underground water and blasting seismic shaking factors,calculations and analyses on side slope stability with different load combinations were carried out,the results show,the stability safety factors of side slope of D-D',E-E'profile with three kinds of load combinations can meet the standard requirements,but F-F'profile shall be broken by instability,it needs a certain protective measures.
