Wanapum Dam Spillway Incident
The Failure, the Response, and
Effects Downstream…..
The c onstruction 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 potenti al failure mode, it was determined lowering the reservoir 27 ft would provi de an acceptable and temporary factor of safety against sliding and rotatio n failure modes.
At a cost of $61M, steel c
abling and rods were used to stitch the dam to the bedrock underneath and i
t became obvious that installation of post-tensioned anchors would be part
of the repair solution. Repairs of the cracked monolith and the strengthen
ing of the remaining monoliths were made in 2014-2015.
Join us f
or a unique look at the repair objectives and approaches used by the Projec
t team of specialized experts to repair the dam. In addition to supplying r
egional 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 s
tructure of regional significance.
