Abstract

The San Francisco-Oakland Bay Bridge is one of the most heavily traveled bridges in the world. The east span of the bridge will be replaced due to seismic safety concerns. The new bridge will be founded mostly on large 1.8 to 2.5-meter diameter, approximately 60- to 100-meter long pile foundations. American Petroleum Institute (API) method was used for pile design, since the selected foundation type is similar to those used for offshore oil platforms and the subsurface conditions are in many ways similar to those in the Gulf of Mexico. Piles foundations will experience tension loads of up to approximately 90 MN and compression loads of up to approximately 140 MN during the design earthquake. Prior to Production pile driving, a cofferdam will be constructed at each pier location, the pilecap footing box will be placed inside and the piles will be driven through the footing box with the use of a 500 to 1700 kilojoule Menck MHU-500 and MHU-1700 hydraulic impact hammer. Based on the Pile Installation Demonstration Project that was conducted in the fall of 2000, a soil-pile setup with time and acceptance criteria was established to accept the production piles.

Design and Construction of Large Diameter Impact Driven Pipe Pile Foundations New East Span San Francisco-Oakland Bay Bridge

The San Francisco-Oakland Bay Bridge is one of the most heavily traveled bridges in the world. The east span of the bridge will be replaced due to seismic safety concerns.
