Abstract：In order to choose a rational form of pile foundation for a large-size construction yard，the shaft force and lateral friction force of the pile with the static load test for the same diameter pedestal piles and the normal piles under the same geologic condition are tested to confirm the design parameter of the pile vertical bearing capacity. This paper analyzes the testing information，and contrasted distributing-characteristic of shaft force and lateral friction force and the force at the end of the pile of the two different pile types，discusses the working- process of the lateral friction force and force at the end of the pile. The load-settlement- characteristic of the pedestal piles and the normal ones is researched. The study indicates that the pedestal pile could bring potential bearing capacity of the supporting layer into play. It could remarkably enhance the pile¢s bearing capacity and reduce the settlement.
