摘要
依托安徽省芜湖市皖南医学院铁山西侧的崩塌边坡治理项目,在勘探、计算和模拟的基础上对边坡的治理和稳定性分析进行研究。通过瑞典法对边坡稳定性进行计算后又基于有限元分析软件Midas-GTS/NX分别建立了自然工况、降雨工况和采用预应力锚杆加固后的降雨工况下的有限元模型。结果表明:在自然工况下的边坡状态为稳定,而在降雨工况下的边坡安全系数为1.029,系欠稳定。根据工况和施工经验对边坡进行预应力锚杆加固后的降雨工况下边坡变成了稳定状态,结果可为类似的崩落边坡研究治理提供借鉴。
This paper relies on the crumbling slope management project on the west side of Tie Shan of Wannan Medical College in Wuhu City,Anhui Province,to investigate the management and stability analysis of the slope on the basis of exploration,calculation and simulation.The slope stability was calculated by swedish method,and then finite element models were established based on the finite element analysis software Midas-GTS/NX for the natural condition,rainfall condition and rainfall condition with prestressed anchor reinforcement respectively.The slope becomes stable under rainfall condition after prestressed anchor reinforcement according to the working condition and construction experience,and the results can be used as reference for similar crumbling slope research and management.
