【摘要】 为研究在交通荷载和环境侵蚀因素作用下桥梁使用性能随时间的衰变规律,通过398座钢筋混凝土桥梁的检测数据,采用时空转换法进行数据分析,拟合出桥梁性能衰变模型,得出了桥梁运营期不同阶段桥梁性能的变化特征.更多还原

【Abstract】 It’s important to study the effect of traffic loads and environmental erosion on bridge service performance according to the growth of bridge age.Based on 398 reinforced concrete bridges’ detection data,service performance decay model of bridge is curve-fitted out by the method of time-to-space conversion,service performance decay characteristic of bridge was drew out in different stages of bridge operating period,which is essential for decision making on bridge maintenance.更多还原
