摘　　要：以郑漯段、安新段、宛坪段桥梁技术状况为基础,以桥梁使用期内不同技术状况下最优养护目标为目的,结合养护费用和养护效果两大因素,建立了预防性养护开始时间预测模型和桥梁预防性养护劣化模型,结合工程案例,运用SPSS软件分析得出预防性养护效果的持续时间与桥梁技术状况之间的函数关系,并借助微粒群优化算法找出桥梁服役期间最佳的养护时机,得出最优综合效益。Based on the bridge technical conditions of Zheng-Luo section,An-Xin section and Wan-Ping section,aiming at the optimal maintenance objectives under different technical conditions during the service life of the bridge,and combining the two major factors of maintenance cost and maintenance effect,the prediction model of the preventive maintenance start time and the deterioration model of the preventive maintenance of the bridge are established,and the functional relationship between the duration of the preventive maintenance effect and the technical conditions of the bridge is analyzed by SPSS software combined with engineering cases.
