Investigation of Slumping Failure in an Earth Dam Abutment at Kotzebue, Alaska.
Abstract
A slumping failure on the upstream side in one area of the water supply reservoir at Kotzebue, Alaska, was investigated. Seven 80-ft (24.4-m) thermocouple strings were emplaced in the dam abutment, and an additional four thermocouple strings were installed behind the dam, extending to a depth of 95 ft (28.9 m) below the bottom of the reservoir. All thermocouples indicated below freezing temperatures at their respective positions. These measurements combined with the drill logs indicate that neither the dam nor the abutment is in immediate danger of failure, but that steps must be taken to stop the sloughing of material in the abutment area. Recommendations are given to accomplish this. (Author)
