WA ACI Chapter Meeting

A 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 Failure, the Response, and Effects Downstream…..

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.

Join us for a unique look at the repair objectives and approaches used by the Project team of specialized experts to repair the dam. In addition to supplying regional hydropower, the direct relationship of this mass concrete structure to insuring public safety, protecting environmental and cultural resources, restoring fish passage, restoring power production come into focus as a structure of regional significance.
