【摘要】 复合土工膜作为一种新型防渗材料,在土石坝工程中已得到了广泛的应用。但关于复合土工膜的防渗机理及防渗效果还缺乏系统的理论研究,本文结合复合土工膜的防渗特性和机理,用有限元法对复合土工膜防渗土石坝进行渗流分析。计算结果表明,土石坝铺设复合土工膜后,改善了渗流情况,提高了蓄水能力。更多还原

【Abstract】 As a new kind of seepage control material, the composite geomembrane has been widely used in embankment dam, yet the seepage control characteristics and effect of the composite geomembrane have not been studied on theory. Based on the seepage control characteristics and mechanisms of the composite geomembrane, this paper analyzes the seepage conditions on the composite geomembrane in seepage control of embankment dam with FEM. The result of calculation manifests that the seepage state is improved and the storage capacity is enhanced after paving the composite geomembrane to the embankment dam.更多还原
