桥梁维修加固后时变可靠度评估与剩余寿命研究

摘要

我国基础设施建设不断发展，公路里程在不断增加的同时公路质量也需要同时提升上来，其不仅仅是为了完善我国整个交通规划，更是为提高我国公路等级打好基础。对桥梁维修加固后时变可靠度进行评语以及研究剩余寿命，其研究意义在于既能够对已经完成加固工作的桥梁进行各项指标的评定以及预测剩余寿命，目的在于能够在了解加固效果的基础上发现更多潜在的问题，从而为后续的维修或加固等工作提供决策上的帮助。%With the development of our country’s infrastructure construction,the highway quality should improve with the increase of highway mileage;it was not only for the perfection of the whole traffic planning,but also for laying a solid foun-dation to improve highway level.The paper explore and analyze the time -dependent reliability evaluation and residual life research after bridge maintenance and reinforcement.The significance of this research was that it can evaluate various index of reinforced bridge and predict residual life,and aimed to find more potential problems on the basic of investigation rein-forcement effect,which can provide decision -making help for the subsequent maintenance and reinforcement work.
