| Abstract: | Combine the actual engineering-composite geomembrane tilting core dam, a seepage instrument is designed to test the leakage due to defects geomembranes. Gained the real leakage due to defects in geomembranes under different aperture of damnification, different water pressure. Analyzing the primary factor that influences the magnitude of leakage due to defects in geomembranes. The study will offer the reference basis for the design of geomembranes. |
| Keywords: | composite geomembranes equivalent aperture leakage duc to defects in geomembranes underlay material composite seepage prevention structures testing phenomenon |
