摘要

In order to study the mechanism of pile-soil interaction during statnamic loading, a FEM program is developed. Since it will also be applied to the statnamic test of piles in lateral direction, batter piles, group pile, and pile raft foundation, the analysis system is formulated in three-dimensional space. Elasto-plastic model is used for the ground material. Joint element is also used for slip at the pile-soil interface. The analysis program uses the direct integration scheme to solve the elasto-plastic analysis in time domain. Laboratory tests of single piles are analyzed to investigate the validity of the developed program. Firstly, the simulations of static load test are done and compared with the measured data from the tests. Then, the simulations of piles under statnamic are conducted under the same ground condition. Finally, the comparisons between the static and statnamic responses of piles are discussed.
