| 摘 要： | 针对碾压混凝土坝渗流特性，采用无厚度缝面单元模拟型进行渗流分析，在不增加网格节点的前提下，不但能高效地刻画出层面和缝面的特点，而且能对具有强透水能力的冷缝或裂缝进行细致的模拟，基本上解决了碾压混凝土坝的渗流建模问题。计算结果表明，采用无厚度缝面单元模型，更加符合坝体的渗流实际情况，提高了求解的精度。

| Abstract: | Taking into account of the defect in the seepage analysis of RCC dams,in this paper the authors mainly adopt the aperture element without thickness model.By this model, the characters of these lift interfaces and lift joint interfaces are showed and the simulation of strongly permeable construction aperture and cracks is precisely done under the condition of the non increasing amount of nodes. The problem of seepage model of RCC dams is fundamentally solved. The results indicate that the solutions are reasonable as a matter of fact and the precision of solutions is enhanced. |
