| The geomembrane is widely used in hydraulic engineering, but it's ease damnified. So,the characteristic of the geomembrane with damnification is studied in this paper.1. Reviewing the history about the application of the geomembrane, and introducing the wide use of the geomembrane in hydraulic engineering with the engineering instances.2. Through the hydraulic puncturing experiment under different material and different opening size, summarizing the rule of stress and strain and the rule of intensity about the geomembrane with damnification.3. Through the calculation , analyzing the influence of anti-seepage of the geomembrane with damnification.4.Analyzing the rule of stress and strain about the geomembrane with damnification in factual engineering with Three-Dimension non-liner FEM.
