大跨径连续刚构桥群桩基础等效模拟计算

Equivalent simulated calculation of long-span continuous rigid-frame bridge pile group foundation

在连续刚构桥的设计中,群桩基础是连续刚构最常用的基础形式之一,考虑桩—土相互作用是建立分析模型的难点,结合套尔河大桥预应力混凝土连续刚构的工程需要,提出了考虑桩—土相互作用的计算方法。

In the continuous rigid-frame bridge's design,the group pile foundation is one of continuous rigid-frame most commonly used underlying forms,considered that the pile-earth interaction is the difficulty of establishing the anatomic model.Combined with the poject need of Tao-er River Bridge prestressed concrete continuous rigid-frame,the paper proposes the calculation method of considering pile-soil interaction.
