摘要
:针对土石坝渗流安全监测中观测项目较少 ,难以分析大坝渗流场的问题 ,通过三维渗流有限元分析 ,分离了大坝坝体、坝基以及两岸岩体的渗流量 ,并建立了基于三维渗流有限元计算的土石坝渗流确定分析模型 .计算实例表明 ,该模型精度较高 .
Aimed at the lack of observation item in safety monitoring seepage flow in embankment dam and the difficulty in the analysis of dam seepage flow field, the separation of seepage flux for dam body, dam foundation and side banks is made by use of FEM for 3 D seepage flow , and the deterministic analysis model of seepage flow is established based on FEM computation. Practical computation example shows that the models precision is higher.
