The geotechnical testing presented in this report was performed to assist in characterizing the likely consolidation behavior, seismic and post-seismic response of the soils beneath the Oakland mole for the proposed alignment of the new span of the San Francisco-Oakland Bay Bridge.The purpose of the simple shear testing was to investigate the possible effects of large cyclic straining, such as might be caused by a significant seismic event, on the subsequent stress - strain properties of the soil. The consolidation testing performed as part of this project was focused specifically on attempting to identify the time rate of consolidation under conditions of predominantly lateral drainage.
