Corrosion of Steel Piles at the Richmond-San Rafael Bridge
Electrical and ultrasonic measurements were made over a period of 3-1/2 years of some steel piling supporting the Richmond-San Rafael Bridge. The results indicate some locations of significant corrosion and warrant removal of samples to verify these tests. The basic cause of the corrosion seems to be an aggressive corrion cell created by the encasement of the upper length of the piles in the concrete footing. It is postulated that electrical polarization techniques appear to be a reasonable non-destructive means for monitoring corrosion behavior. However, the polarization measurements relate total amount of metal loss and not pit depth or loss that would be concentrated at the interface of the steel pile and the concrete pier. For this reason, sections of piles should be removed from the structure and measured for corrosion loss.
