| Abstract: |
| Theoretical analyses of the strength of overlying voids of geomembrane, used as anti seepage materials covered by soil in the embankment dam, are carried out based on membrane theory and arch action of soil. Calculation formulas, charts and tables to calculate design parameters are given out. |
| Key words: membrane theory,arch action,strength of overlying voids,design parameter,geomembrane |
