PERFORMANCE OF SAN FERNANDO DAMS DURING 1994 NORTHRIDGE EARTHQUAKE

The Lower and Upper San Fernando Dams of the Van Norman Complex in the San Fernando Valley, California, were subjected to strong near-source ground motions during the 1994 Northridge and 1971 San Fernando Earthquakes. These earth dams, which were out of service and retained only a few meters of water in 1994, cracked extensively and settled due to the liquefaction of their hydraulic fill. The Lower San Fernando Dam moved over 15 cm upstream as the hydraulic fill liquefied beneath its upstream slope. The Upper San Fernando Dam moved even more and deformed in a complex three-dimensional pattern. Two useful case histories for the geotechnical engineering community have come from the responses of the Lower and Upper San Fernando Dams during the 1994 Northridge Earthquake, although less significant than the 1971 cases.
