    摘要:

    以宁波市环城南路下穿铁路斜交框架桥项目为依托,利用ANSYS有限元软件建模,分析了斜交框架桥在养护期的应力场分布特点与规律,并得出了斜交角度对其应力场分布的影响。同时进行现场试验,将测试结果与计算结果进行对比,验证了计算结果的可靠性,为今后斜交框架桥的设计与施工优化提供参考依据。

    Abstract:

    Based on the project of South Huancheng Road through Railway Skew Frame Bridge in Ningbo, using ANSYS finite element software to model, the stress field distribution characteristics and rules of skew frame bridge during maintenance period are analyzed, and the influence of skew angle on its stress field distribution is obtained. At the same time, field tests are carried out to verify the reliability of the calculation results by comparing the test results with the calculation results, which provides a reference for the design and construction optimization of skew frame bridges in the future.
