Seismic Stability Evaluation of Folsom Dam and Reservoir Project. Report 5. Seismic Stability Evaluation of Dike 5
Abstract
The man-made water retaining structures at Folsom Dam and Reservoir Project, located on the American River about 20 miles upstream of the city of Sacramento, California, have been evaluated for their seismic safety in the event of a Magnitude 6.5 earthquake occurring on the East Branch of the Bear Mountains Fault Zone at a distance of about 15 km. This report documents the seismic stability study of Dike 5, one of the eight homogeneous saddle dikes at the Folsom Dam Project. The evaluation process involved extensive review of construction records, field and laboratory investigations, and analytical studies. Dike 5 is expected to perform well if subjected to the design earthquake motions. Due to similarities in the embankment cross sections and in foundation conditions with Dike 5, the other seven dikes at the Folsom Project are also expected to perform satisfactorily during the design earthquake. Keywords: Earthquake resistant structures; Earthquakes and hydraulic structures; Folsom dam safety; Geologic faults.
