【摘要】 本文基于饱和-非饱和渗流数学模型,采用有限单元法对飞来峡水利枢纽工程纵向围堰典型剖面进行渗流数值模拟,分析降雨及非稳定渗流对渗流场的影响,简捷地得到了较全面、准确的参数分布。本文还提出一个简易的(Κ_γ-Ψ-θ)曲线拟合方法从有限的观测试验中获取所需参数。本模型及程序可以不作特别的修改而应用到具有复杂地质分布和边界条件的各种实际渗流工程。更多还原

【Abstract】 A saturated-unsaturated seepage pattern is developed to analyze a typical section of the longitudinal cofferdam in Fei-Lai-Xia Hydrocomplex Project, using the simplified finite element method. The effects of the rainfall and unsteady seepage flow to the field are analyzed. Numerical results give a relatively apprehensive and accurate data; distribution. An easily applicable method to obtain the parameters from the soil test data is presented. The model can be directly extended to various seepage engineerings with complex boundary conditions and geological distributions without any specific reform.更多还原
