摘要
对于大面积或全库盘使用土工膜防渗的水库,土工膜防渗体渗透特性的分析是工程设计和施工的一项重要工作,对利用和管理库区水资源具有重要意义.从水量平衡角度,采用达西定律对库盘大面积土工膜防渗体的渗透特性进行研究,分析库盘大面积土工膜防渗体产生的破损孔洞对土工膜渗透特性的影响,计算大面积土工膜防渗体的渗透量和渗透系数,从整体上得出大面积土工膜防渗体渗透特性的分析方法.结合工程实例,计算其土工膜防渗体的渗透量和渗透系数,得出土工膜防渗体的渗透规律.
For large area geomembrane seepage prevention of reservoir,leakage analysis of leakproof geomembrane is an important work in engineering design and construction,and it is meaningful to the utilization and management of water resources of the reservoir area.From water balance view and on the basis of Darcy′s law,we analyze the characteristics of prevention of large area geomembrane,calculate the leakage capacity and coefficient of large area geomembrane,and then find the method of analysing the large area geomembrane leakage on the whole.With practical work,we study the leakage capacity and coefficient of leakproof geomembrane,and obtain seepage regulation of geomembrane as impervious body.
