桥梁高墩稳性定问题的计算长度参数研究

The Study of the Effective Length Factor of High Pier in Bridge Stable Problem

本文主要对桥梁高墩稳定性分析中的计算长度参数进行了分析研究,以预制装配式预应力混凝土连续梁桥为例,采用Midas有限元软件建立计算分析模型,考虑了墩径和墩高以及高墩所处的不同施工阶段等参数变化对墩身稳定性分析计算长度系数的影响,通过对比不同状况的计算结果得出结论,相关研究成果可供工程技术人员参考。

In this paper,the effective length factor of high pier has been studied in bridge stable problem. The prefabricated pre-stress reinforce concrete continuous girder bridge is modeled by Midas which is a finite element software. Considering the differences of diameter,length and construction stage,the effective length factor of high pier is analyzed. The results can be used as reference by engineer.
