Abstract: Using direct shear friction and consolidation test to determine the load transfer parameters of soil surrounding the pile in different depth or beneath the pile tip, based on the theory of pile soil interaction, the relationship of load settlement and the law of load transfer have been studied. A new nondestructive method that combination with indoor test and theoretic analysis is presented. Comparision is made between the results obtained by the proposed method and the lo ad test data and close agreement has been found, thus verifying the reliability of the proposed method.
