摘要

The Salinas River Diversion Facility (SRDF) is located on the Monterey Bay near the coastal town of Marina, California. The project components include an inflatable gate diversion structure, a vertical-slot fish ladder, an intake structure with fish screens, a pump station, and a transmission pipeline connecting into an existing distribution pipeline system. Extensive liquefaction and lateral spreading were documented along the banks of the Salinas River following the 1906 San Andreas earthquake. Geotechnical investigations at the site confirmed the presence of loose liquefiable soils and the need for special foundation designs and remedial measures to ensure structural stability. This paper presents the project background, geotechnical site conditions, seismicity and liquefaction hazards, and key design features of the SRDF including the foundation improvement program and diversion dam structure and foundation designs. The paper also describes the construction phase, with a focus on the river channel foundation improvement activities.
