| Summary: | The OA-5 Dam is one of the earth structures of the EOL (Eastman–Opinaca–La Grande) project within the 'La Grande' hydro-electric complex at James Bay, Quebec. Three rivers were diverted to the La Grande River to increase the hydro-electrical potential of the LG-2 power plant. Dam OA-5 (32.3 m high and 385.6 m long) has a zoned section with an impervious central core, and rests on bedrock.The paper describes the different construction phases of the dam, i.e., Opinaca River diversion and closure, foundation treatments, earth and rockfill placement, quality control of materials, and the behaviour of the dam during and after filling of the reservoir. Keywords: closure, compaction, construction, dam, diversion, earth and rockfill, glacial till, grain size analysis, gravel, river, sand. |
