摘要
堆积体削坡开挖后的稳定性对水电站的施工及以后的正常运行至关重要,通过采用大型通用有限元软件ANSYS对该堆积体的典型剖面进行了二维稳定性分析,并结合现场监测数据的分析,使模拟结果和监测分析结果相互印证,提高了模拟结果的可信度。在此基础上根据模拟结果的分析,得出该堆积体整体稳定性较好,但可能会发生浅表层滑动破坏的结论。
The stability after cutting-slope excavation of congeries is vital to the construction of a hydropower station and its following normal operation.The two-dimensional stability of the congeries＇ typical section is analysed by adopting the finite element software ANSYS.Combining with the monitoring data,the result of simulation and the result of monitoring analysis are confirmed mutually.In addition,the credibility of the simulation result is improved.According to the analysis for the simulation result,it can be obtained that the global stability of the congeries is fine,but the sliding failure will perhaps occur in superficial layers.
