Static load test is a most direct way to determine bearing capacity of large diameter pedestal pile. Because of the difficulties in loading process and high test cost

load test is not feasible in practical engineering. In general

bearing capacity can be obtained by means of the reduction of pile tip and side resistance based on the empirical parameter method of Technical Code for Building Pile Foundation in large diameter pedestal pile design. In this way

the bearing capacity of large diameter pedestal pile can not be well used. Based on the modifying of technical specification for large-diameter pedestal cast-in-place pile foundation

the test data of piles are statistically analyzed. The characteristic value of tip resistance and shaft resistance are presented using for reference from Technical Code for Building Pile Foundation and empirical values given by local codes of Beijing

Tianjin

Zhejiang

Fujian and Guangdong. The characteristic values of tip resistance and shaft resistance given in the present paper are compared with the measured values of test pile and calculated values obtained by Technical Code for Building Pile Foundation. It is found that the characteristic values proposed in the present paper are reliable and applicable in practical engineering.
