摘要
位于云南玉溪师范学院内的一处陡坡,为了防止不良地质灾害的发生,影响陂肩道路和周边高层楼房的正常使用,危害人们的生命财产安全。本文采用MIDAS/GTS NX有限元软件对该边坡的稳定性进行数值模拟分析,得到原始边坡稳定系数为1.278,处于基本稳定状态,但仍未达到该边坡工程所规定的安全系数,采用锚杆+排水沟+生态护坡的方案对边坡进行综合治理后,稳定系数上升到1.628,提高了边坡稳定性,减小了安全隐患。验证了锚杆对岩质边坡加固的可行性,对岩质边坡的稳定性分析和治理具有一定参考价值。
A steep slope located in Yuxi Normal University,Yunnan Province,in order to prevent the occurrence of adverse geological disasters,the normal use of shoulder road and surrounding high-rise buildings will be affected,which will endanger people’s lives and property.In this paper,MIDAS/GTS NX finite element software is used to carry out numerical simulation analysis of the slope stability,and the original slope stability coefficient is 1.278,which is basically stable,but it still does not reach the safety coefficient specified by the slope engineering.After the comprehensive treatment of the slope with bolt+drainage ditch+ecological slope protection,the stability coefficient rises to 1.628,which improves the slope stability and reduces the security risks.The feasibility of rock slope reinforcement by anchor bolt is verified,which has certain reference value for stability analysis and treatment of rock slope.
