Seawall Movement and Piling Design at the San Francisco Waterfront
Publication: Ports 2019: Port Engineering
ABSTRACT
The San Francisco Fire Department is acquiring a new floating fire station. A new pile- supported pier structure will connect to the fire station with an access ramp. The new pier piles will extend down through the existing 100+ year old seawall rock embankment, through a weak and thin, 10 ft (3 m), layer of consolidated bay mud below the embankment, into a stiffer alluvial layer and bedrock below. This paper discusses methods and findings for this project, including challenges encountered and suggestions for future projects. Topics include: soil dynamic shear strength obtained from testing; estimated seawall seismic movement; piling response; comments on ASCE 61 design requirements; methods and findings for evaluating the pile pinning strength; and seawall bulkhead arching across the site due to adjacent larger seawall movements.
