Study on Application of Strengthening Method and its Optimization on Continuous Box Girder Bridge

Abstract:

Article Preview

According to the mechanical characteristics of the continuous box girder bridge and the disaster situation, a combined strengthening method was used to strengthen Yingyugou Viaduct. The 3D numerical simulation method was used to analyze the effectiveness of external prestressing reinforcement technology, external sticking steel plate method, increasing section method and gluing CFRP method. Based on the analysis, the original design scheme was optimized to take advantage of each strengthening method, and improve the overall effectiveness of the combination strengthening method.
