| 摘 要： | 提出了一种新的堆石坝防渗结构,即复合防渗面板,并采用三维有限元方法对复合防渗面板堆石坝的应力、变形进行模拟计算分析,通过对坝体位移、坝体应力、钢筋混凝土面板挠度及应力、复合土工膜的变形的计算,得出了有价值的结论,为复合土工膜及复合防渗面板的推广应用提供了理论参考依据。

| Abstract: | In this paper, a new structure, complex prevented-seepage face, is developed. The stress and the deformation of the dam and the concrete-face and the strain of the complex geomembrane have been calculated by finite element analysis, and some useful conclusion has been adopted. This paper has developed theory for use of complex geomembrane and complex prevented-seepage face. |
