摘要

为了探讨土工膜的微观结构特性和对其破坏渗漏机理做微观评价，采用光学显微镜和电镜对在各种不同延伸率受力状况下的土工膜微结构进行了分析。其研究的难点为拍摄一定延伸率下土工膜微结构技术及显微图像的数据处理。由显微成像得知：光镜与电镜成像结果是一致的，土工膜破坏不仅与颗粒杂质有关，而且与结构本身塑性有关。

Abstract

For researching into the microstructural peculiarity of geomembrane and proceeding to the next step of evaluating the mechanism of seepage in microcosmic side

optical and electronic microscopes are used to analyze the microstructure of geomembrane. The difficulty is taking a series of pictures of geomembrane in definite condition and making picture processing. By analyzing geomembrane microstructure

it is indicated that the results from optical and electronic microscopes are combined; moreover

the structure impure particles and plasticity defects are the major factors

which make geomembrane damage.
