摘要：
A caisson type pile foundation with reinforcing bars has been proposed by Matsuo and Ueno (1989). This foundation was developed for increasing uplift bearing capacity of transmission towers and others. In the present study, the mechanism of reinforcing effect of such types of foundation is numerically investigated by finite element analysis. The present analysis takes into account not only elastoplastic characteristics of geomaterials but also the stiffness of reinforcements and the frictional behavior between soil and reinforcement and soil and pile. The analytical results clarify the mechanism of the uplift bearing capacity and give information about the most suitable arrangement of reinforcements.
