Seismic Stability Evaluation of Folsom Dam and Reservoir Project. Report 2. Interface Zones
Abstract
The man-made water retaining structures at the 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 study of the interface zones where the Left and Right Wing Dams envelope the Concrete Gravity Dam. The evaluation process involved extensive review of construction records, field and laboratory investigations, analytical studies and an assessment of subsurface conditions. It has been determined that the interface zones are stable in response to design earthquake loads.
