SEISMIC RETROFIT OF LITTLEROCK DAM

Littlerock Dam, located in the Angeles National Forest in southern California, was originally designed and constructed as a multiple-arch structure. Throughout its life, there have been concern and controversy about the adequacy of its design, overall stability, and safety because the dam is located 1.5 miles south of the San Andreas fault. To provide adequate seismic stability of the dam, Woodward-Clyde Consultants of Oakland, California, developed a rehabilitation design that consisted of economical uses of (1) roller compacted concrete (RCC) to construct a gravity section between and around the downstream portions of the existing buttresses, and (2) bonded steel fiber reinforced shotcrete to stiffen the arches of the existing dam.
