| 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. |
