| Abstract: | The DM-8 W polyvinyl chloride geomembrance is a new material produced recently withthe properties of wide size and good physical performances. This paper studied application of thegeomembrance in seepage control of the earth and stone mixture dam and the structure form of theseepage Control layer. The wave protection work face is merged with the geomembrance protectinglayerby the covering of movable thin prefabriCated concrete blocks and sandy filling. The joints amongthe blocks are designed as wedge or obligue for against the passble cracks between plates. The economicand reasonable properties of the structure are discussed from the views of reP8iring, stability and agingcontrol. |
