Detection and Evaluation of the Bearing Capacity of Railway Steel Plate Girder Bridges

To ensure the safe operation of existing railway bridges, it is necessary to conduct comprehensive inspections of their bearing capacity and actual working conditions on a regular basis. In this paper, taking the 2# steel plate girder bridge on Qinglv Branch Heihe as an example, the appearance inspection, pier and abutment strength test, static load test and dynamic load test were carried out on this steel plate girder bridge, and the content and method of the comprehensive test of the steel plate girder bridge were explained; Based on the test results, the working condition of the bridge was evaluated, hoping to provide reference and reference for other similar bridge type inspection and reinforcement work.
