Abstract:
Describes the deficiency investigation of British Columbia Hydro's Jordan River Dam, and design of the selected rehabilitation scheme. The investigation involved foundation exploration, field nondestructive testing of the buttress sections, removal and testing of concrete samples, and dynamic structural analyses. The main conclusion was that the buttress dam would likely fail under an earthquake with a horizontal cross-canyon ground acceleration of 0.05 to 0.10 g. The failure of the dam would result in uncontrolled release of the reservoir, which was considered unacceptable.
