This paper describes the evaluation method of soil springs in the design of the pile foundation in which a pile is expressed with beam elements and the ground with soil springs of horizontal and vertical directions. The proposed model of soil springs is based on the concept of the subloading surface model that realizes a smooth transition from elastic state to plastic state of the soil. Simulation analyses of lateral and vertical loading tests in an actual ground were carried out by using the proposed model. The computed results show a fairly good agreement with the test results.
