摘　　要：进行了不平衡弯矩作用下有受拉桩的厚承台实验与有限元研究,表明该种承台可以因有梁作用而发生弯曲破坏,而受弯曲作用的同时,又因有拱作用而使得空间桁架的传力体系依然存在。梁拱作用并存在厚承台中具有一定的普遍性。The study of the deep pile cap with a pull pile under an unbalanced bending moment is processed, based on the test and finite element method. The research indicates that this kind of pile cap may induce bending failure due to the beam action, and at the same time, it still acts as a load transfer system of the spatial strut-and-tie due to the arch action. It is definitely universal that both the beam action and the arch action exist in the deep pile cap.
