MISSION DAM AN EARTH AND ROCKFILL DAM ON A HIGHLY COMPRESSIBLE FOUNDATION

This paper deals with the design, construction, and performance of an earth and rockfill dam on the Bridge River in British Columbia. The site is underlain by two very pervious aquifers. Under the major portion of the dam site these are separated by a thick stratum of highly compressible clay. A deep grout cut-off through the lower aquifer, extending to a maximum depth of about 520 ft, and a sheet pile cut-off through the upper aquifer control see page through the foundation. The nature of the available construction materials and the anticipated large differential settlements (up to 15 ft) led to the design of a zoned types of embankment. Significant details of construction and performance of the dam during the first 3 years of service are described.
