双曲拱桥是桥梁改造中的常见桥型。介绍粘贴钢板法在加固双曲拱桥中的应用,并用有限元软件MIDAS Civil对加固前后的结构受力状况进行分析。结果表明,运用粘贴钢板法加固后的双曲拱桥,桥梁受力状况得以改善,承载力明显提高。 Double curved arch bridge is a common bridge in the transformation. This paper introduces the application of the steel plate method in the reinforcement of double curved arch bridge, and analyzes the structure stress before and after reinforcement by the finite element software MIDAS Civil. The results show that with the double curved arch bridge strengthened by the method of affixed steel plate, the stress condition of the bridge can be improved and the bearing capacity of the bridge can be obviously improved.
