摘要
分别研究了整体锈蚀和局部锈蚀两种锈蚀模型下钢筋混凝土桥梁的服役可靠性。同时 ,讨论了钢筋锈蚀速度、活载参数和恒载参数对服役可靠性的影响。桥梁服役期间可靠性评价对于预测服役寿命和经济、科学地安排维护时间及维护方案都具有重要意义。
Reliability is estimated considering two corrosion models uniform corrosion and local corrosion.The effects of parameters such as variability in dead and live load and corrosion rate are studied.The results can be used to predict the service life of deteriorating RC bridges,and to develop rational and optical lifetime reliability based maintenance strategies for these bridges.
