摘要
首先针对大江大河截流抛投材料的尺寸及截流施工过程的具体安排 ,对于堆石体及大粒径材料渗流规律已超出了达西定律的实际现象 ,分析了截流戗堤的渗漏特性 ,将截流戗堤按渗流参数的大小范围分为不同的区段 ;其次以渗流的控制方程为基础 ,从非线性的渗透规律出发 ,利用有限单元法建立了截流戗堤的渗流计算模型 。
Firstly, in light of the size of material used in large river closure and concrete planning in closure construction process, the seepage characteristics of embankment are analyzed; and the berm_dam for rive closure is divided into different parts according to seepage parameter. Secondly, on the basis of embankment_seepage control equations and nonlinear seepage rule, the embankment seepage model is established by using finite element method and verified by the experiment data
