多跨拱形V墩连续刚构桥设计及影响参数分析

Design and Influence Parameters Analysis of a Multi-span Continuous Rigid Frame Bridge with Arch Shape V-piers

为了研究某拱形V墩预应力连续刚构桥的受力特性,对该桥型的设计和该结构的受力体系进行探讨,采用有限元计算程序,对结构进行了建模计算,并重点分析了边中跨比、桩土作用、地基强度等参数对整个结构内力的影响,得出了该结构受力特点,可供同类型桥梁设计施工提供参考。

In order to study the characteristics of a prestressed continuous rigid frame bridge with arch shape V-piers, the design concept of this kind of bridge was discussed, the mechanical system of this type of bridge was defined, the structure internal force of the bridge was calulated by finite element method. The effects of the ratio of center span and side spans, pile-soil interaction and foundation stiffness on the structure internal force were analyzed, and the mechanical characteristics of the structure were concluded, which provided reference for the same type of bridge in design and construction.
