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.

Key words: geomembrane, microstructure, elongation, seepage, microscope
