Analytical and Field Estimates of Shaft Resistance in Socketed Piles: Bandra-Worli Sea Link, Mumbai
Rajesh H. Gajjar, Sunil S. Basarkar, Dilip M. Dewaikar
A load transfer program AXPILE was developed for simulation of the load-movement characteristics of socketed piles of the Mumbai region. This program used empirical relationships for ultimate shaft resistance at pile-rock interface recommended by Zhang and Einstein (1998). According to their recommendation, ultimate shaft resistance at pile-rock interface is related to the square-root of uniaxial compressive strength of intact socket material by a parameter C, which ranges from 0.4 for smooth sockets to 0.8 for rough sockets. Results of three instrumented pile load tests were compared with the AXPILE generated results. The comparison of analytical and field estimates of the unite shaft resistance confirm the recommendations of Zhang and Einstein (1998) on the unite side shear parameter Cf, which was found to be in the range of 0.35 to 0.67.
