| 摘 要： | 运用固定网格的结点虚流量法、非均质成层材料单元、缝面无厚度平面单元等，对江垭碾压混凝土坝渗流场进行了建模与分析研究，在反演出坝体几种主要筑坝材料的渗透系数张量的基础上，再通过对多种典型工况的敏感性反馈计算，进一步研究江垭大坝渗流场的渗流特性和渗流场水头分布规律，进而提出碾压混凝土坝防渗与排水渗控方案设计的建议。

| Abstract: | By use of the node virtual discharge method and introduction of inhomogeneous stratified material elements and planar non-thickness elements, a numerical model is established for analysis of the seepage field of the Jiangya roller compacted concrete gravity dam. Based on the back-analysis of the tensor of permeability coefficients of several main materials of the dam and respective sensitive feedback calculations under several typical operation conditions, a study is made on the seepage characteristics about the distribution of the hydraulic heads and uplifts in the dam body and foundation, so as to verify the reasonability and effectiveness of the seepage control scheme. |
