WA ACI Chapter MeetingA special Eastern Washington WA ACI Chapter meeting with a special Networking invitation to students at Gonzaga, WSU and Eastern WA University. Wanapum Dam Spillway Incident The construction and repair of mass concrete structures is a complex topic. The repair of an existing and active dam brings the discussion to a whole new level. On February 27, 2014, a 2-inch (5 cm) wide crack was discovered on the Wanapum Dam on the Columbia River by inspection divers on one of the 65 ft. tall concrete monoliths that make up the spillway of the dam. This could be a problem….. To avoid potential failure mode, it was determined lowering the reservoir 27 ft would provide an acceptable and temporary factor of safety against sliding and rotation failure modes. At a cost of $61M, steel cabling and rods were used to stitch the dam to the bedrock underneath and it became obvious that installation of post-tensioned anchors would be part of the repair solution. Repairs of the cracked monolith and the strengthening of the remaining monoliths were made in 2014-2015.
