| Abstract: | The authors have carried out large-scale water pressure breakdown tests, integrative cushion layer, transition layer and geomembrane impermeability tests and large-scale compression tests on various cushion layer materials by selecting compound PE membrane materials with various specifications that are being widely used at the present time based on the seepage control treatment in the Dameitian karst reservoir area in Luoping county, Yunnan province. The paper has expounded and verified the reasonableness of the selected compound geomembrane and its specification and also recommended the suitable cushion material gradation and the transition layer material as well. In addition the paper has obtained through the study some important engineering properties related to the geomembrane, providing scientific basis for the design of seepage control system for other similar reservoirs and projects. |
