摘要
群桩基础是连续刚构最常用的基础形式之一,分析探讨了群桩基础的几种建模方法,给出了建模思路和参数取值。结合苏通大桥辅航道桥预应力混凝土连续刚构的工程需要,提出了考虑群桩基础与上部结构共同工作的计算模型,并将计算结果与不考虑桩基的模型计算结果进行了对比分析,计算方法对类似工程有直接参考价值。
The group pile foundation is one of the foundation types that are most commonly used for continuous rigid-frame bridge. In this paper, several methods for establishing calculation models for the group pile foundation are analyzed and discussed, and the considerations for establishing the models and ways to select parameters for the models are provided. To cater for the needs of the prestressed concrete continuous rigid-frame bridge of Sutong Bridge over the secondary navigable channel, the calculation models that take into account of joint action of both the group pile foundations and superstructure are proposed, and the calculation results with the models are then analytically compared to those disregarding the action of the pile foundations. The calculation methods herewith can serve as direct reference to the calculation of similar structures.
