[Abstract]:Heavy haul railway transportation is popularized and applied in more and more countries because of its large capacity and high efficiency. Because of the increase of axle load of unit train, the improvement of train traction quality and the increase of driving density, The disease of railway bridge is gradually revealed. This paper aims at the application and implementation of heavy haul railway bridge management information system, focuses on studying the method of dynamically mastering the health condition of heavy haul railway bridge, establishing the collection of bridge information and the evaluation of the state of the bridge. A management system that integrates decision-making, This paper mainly includes the following aspects: 1) the influence of heavy haul transportation on existing railway bridges and the analysis of bridge diseases. Correlation of heavy haul railway bridges under the action of different axle load trains. The mechanical parameters are analyzed and studied. The mechanical characteristics of the bridge under the heavy load and heavy load transportation are summarized, and combined with the operation of the heavy haul railway, This paper analyzes and summarizes the deterioration assessment management and special inspection assessment management of heavy haul railway bridge, and studies the evaluation method of bridge state based on appearance detection, and focuses on the comprehensive evaluation method of bridge deterioration state. Based on Analytic hierarchy process (AHP) and according to the characteristics of heavy-haul railway bridges, a bridge deterioration evaluation model and evaluation system are established. The practicability of this method is verified by evaluating the deterioration status of two bridges on the heavy-haul railway. This paper studies the evaluation method of mechanical performance based on special inspection of bridge, especially the method of evaluating the working condition of bridge by operation performance test, and puts forward the evaluation flow of bridge operation performance test. According to the influence factors of the limit value of each specification, the automatic realization method of comparing the measured value with the standard value is put forward. The design and development of the heavy haul railway bridge management information system is presented. The automation of maintenance and repair project priority, the design of each component module and function of the heavy haul railway bridge management information system, the realization of the heavy haul railway bridge information query, A management software system that prioritizes status assessment and maintenance and maintenance projects.
