Study and Application of Bridge Degradation Model and Maintenance Decision
In the paper,the research results of Chinese and foreign scholars on the law of bridge performance degradation and maintenance strategy are analyzed,the research progress of bridge degradation prediction model are introduced from the perspectives of mechanic-based degradation and statistical law based degradation,and the establishment and solutions of bridge maintenance and repair decision model are summarized.The classic bridge management systems at home and abroad are elaborated in terms of the basic structure of bridge management system,evaluation and decision module,maintenance countermeasures and cost calculation,and maintenance program optimization.The research progress of bridge degradation models and maintenance management decisions at home and abroad that concluded in the paper can help bridge management personnel obtain the optimal strategy and realize efficient and scientific bridge management in the face of many uncertainties and financial constraints,and can provide useful reference for scientific bridge maintenance strategies.
