Research on Technical Condition Assessment System and Method of Rail Transit Bridges
The technical condition assessment system and testing indexes for rail transit bridges are built to provide a basis for the testing and assessment of rail transit bridges.On the basis of the testing specifications of highway,municipal and railroad bridges,the structural characteristics and loading characteristics of rail transit bridges are studied.A technical condition assessment method for rail transit bridges is proposed.The testing indexes of rail transit bridges based on highway bridges are clarified.A complete and feasible set of testing and assessment techniques is formed.By selecting a typical girder rail transit bridge project,the evaluation method established by the study is used to evaluate the technical condition of the project structure.The results show that the assessment results of the method and the original method are basically the same,and the former better reflects the key concerns in the management of rail transit bridges,which verifies the applicability and relevance of the method.
