摘　　要：针对拟建桥梁结构与现役桥梁结构的不同之处,基于不同的鉴定基准期,系统地总结分析了荷载效应与抗力在后续使用期内随时间的变化规律。根据实际工程中的检测值,在进行计算分析时,讨论了对抗力预测模型的修正,为结构的可靠性分析提供了一种较为完整的荷载、抗力计算方法。This paper systemically summarizes and analyzes the time-variant changes of load effect and resistance of existing reinforced concrete bridges in their later service life period in accordance with the differences between the existing reinforced concrete bridges and the bridges to be built, and the different evaluation time. Based on the inspection and test values of the actual bridges, at the same time the calculation and analysis are conducted, the modifications of the prediction models for the resistance are discussed, and considerably complete calculation methods for the load and resistance are provided for reliability analysis of the existing structures. 
