Abstract
Crane Valley Dam is located on the North Fork of Willow Creek in Madera County, California, and is owned by Pacific Gas & Electric Company (PG&E). The results of seismic stability analyses performed in 2005 and 2006 showed that the dam’s hydraulic fill embankments would experience large deformations during and after the earthquake shaking postulated for the site. To improve the seismic stability and performance of the dam, PG&E initiated the Crane Valley Dam Seismic Retrofit Project (Project), which includes placing new rockfill buttresses on the upstream and downstream slopes of the dam, constructing internal drainage improvements, reinforcing portions of the dam’s concrete core wall, and raising the dam crest. Project components were designed to meet seepage control and seismic stability criteria and to accommodate existing facilities, limited site access, seasonal reservoir operations, and environmentally sensitive areas within and adjacent to the Project site. Engineering analyses included static, seepage, and dynamic finite element analyses to evaluate the potential for liquefaction of hydraulic fill materials and post-earthquake stability of the retrofitted dam embankment. Construction of the Project began in October
