Doing Well Railway Bridge Health Management Based on Detection Technology

Abstract: With the rapid development of China's railway sector, a large number of railway bridges are facing the demand for scientific health management. Challenges in the field of railway bridge health management include different types of natural disasters, various types of deterioration of old bridges, the adoption of a large number of new technologies for newly-built bridges, and insufficient intelligence of detection means. The technical system of railway bridge health management includes not only the organization and management means, but also the detection technology, evaluation technology, prediction and early-warning technology and maintenance decision-making technology. In terms of management, it is necessary to establish the management concept based on reliability theory, improve the standard system and establish an integrated information technology platform; in terms of technology, it is necessary to develop intelligent detection and monitoring technologies, develop risk assessment and reliability assessmettheories, study bridge operation performance assessment technology, predict the residual life of bridge in detail, give scientific early warning to grave accidents, guide scientific operation and maintenance decision-making based on the concept of full life cycle cost, and develop condition-based repair and preventive maintenance.
