Geosynthetics lining design on slopes of water reservoirs in mountains
The paper describes the design and construction of large reservoirs under mountain climat conditions dedicated to artificial snow making for ski resorts. Typical stress conditions are listed. The design of the geosynthetic system comprises a protective drainage sub-layer called hereafter 'geocomposite drain', then the lining geomembrane itself and then the protective and armoured top-layer called 'geomattress'. The paper describes the design of the different geosynthetic layers in respect with their main function. Parts of the design highligthed herebelow are such as anti-puncture, in plane drainage capacity, thermal behaviour of the geomembrane, strength and anchor on slopes. The friction angles inbetween the geosynthetic layers are considered. The hydrostatic stress above the geosynthetics is currently 100 kPa (10 m water) whereas the slopes reach 30 m with a 26 deg of angle. The geomembrane is totally or partially covered with a 40 cm soil layer. The largest volume of storage considered here are about 100000 cubic meter situated at 2000 m above sea level in mountain climate and geotechnical conditions. Ice impact on the geomembrane is reported. The first project following that design was built in 1997 and behaves very well without any need of repair.
