摘要
为了研究土塞效应对大直径PHC管桩的影响,通过建立开口桩和闭口桩的桩土有限元模型,在充分考虑桩土接触的情况下,对管桩进行竖向加载,得出了在不同荷载下桩土作用的荷载传递规律、土塞的受力特性,对大直径PHC管桩土塞效应的作用机理研究有较好的参考价值。
In order to study the effect of soil plug on large diameter PHC pipe piles, set up the finite element model of open pile and closing pile with soil, in the case of fully considering the pile soil contact, undering vertical load, to obtaine the load transfer law of piles and soil, and the stress of the soil plug features. To provide the reference value of the study of large diameter PHC pipe pile soil plug effect.
