中文摘要：

中国自1980s建设土工膜防渗的大坝水库以来,历经30多年的实践,建成一批具有代表性的工程;国内对PE、PVC材质防渗土工膜的主要物理力学特性已经掌握,对防渗膜的结构运行特性研究已取得初步成果,基于基础力学的设计方法得到普遍应用,防渗膜结构数值模拟分析水平已有较大提高,防渗土工膜结构施工工艺趋于成熟,最近实施的相关设计规范对膜防渗大坝高度的限定基本解除。

英文摘要：

A series of representative projects of reservoirs and dams with impermeable barrier of geomembrane have been built through the continuing practice for more than 30 years since the 1980s in China. Up to now, the main physical and mechanical characteristics of PE and PVC geomembranes have been known well. The basic achievements have been gained on characters of structure with impermeable barrier of geomembrane. The design approaches based on the basic mechanics have been applied. The analysis ability of digital simulation have been strengthened, and the construction technology has been improved on structure with impermeable barrier of geomembrane. The limitation of height of dams constructed by impermeable barrier of geomembrane has been basically relieved the latest codes and specifications.
