摘要：In order to guarantee the expected service life of the bridge and reasonably allocate limited maintenance fund, this paper focuses on the timing of the bridge maintenance. By studying the degradation mechanism of bridge structure, we establish the degradation model of concrete bridge structure and the multi-objective optimization model. Through minimizing the maintenance cost, the bridge maintenance time can be determined. Furthermore, according to the environmental impact and the effect of various maintenance methods, we develop the maintenance countermeasures list, which builds up a good basis for the scientific quantitative analysis of preventive maintenance.
