矮墩式刚构桥受力行为仿真分析

Simulation analysis and research on the behavior of the low pier rigid bridge

矮墩式刚构桥与常见的大跨、高墩连续刚构桥存在着较大差异,由于跨度小、墩较矮、约束强,导致温度、支座沉降等因素对结构的受力行为影响较大,文章通过有限元计算,对矮墩式刚构桥受力行为进行分析,给出了相应结论和建议.

The low pier rigid bridge is different from long span high pier continuous rigid bridge.Because of its characters,the behavior of the low pier bridge is intensively affected by the temperature and the asymmetry settlement of foundation.In this paper,according to the finite element calculating,the behavior of the low pier bridge is presented.Finally,the corresponding conclusion and suggestion is given.
