摘要
为评估在役公路隧道的剩余寿命,建立一种基于荷载-结构法的在役公路隧道剩余寿命评估模型;以复合式衬砌在役公路隧道为研究对象,分析在役公路隧道常见病害及其对剩余寿命评估模型基本参数的影响。结果表明:基于荷载-结构法的公路隧道剩余寿命评估模型可实现对在役公路隧道剩余寿命的评估,对掌握隧道目前工作状态、隧道维修养护等方面具有重要意义。
In order to evaluate the remaining life of the in-service highway tunnel,a remaining life assessment model of the in-service highway tunnel was established based on the load-structure method.Taking the composite lining in-service highway tunnel as the research object,the common diseases of the existing highway tunnel and its influence on the base parameters of the remaining life assessment model were analyzed in the current study.The results show that the remaining life assessment model of highway tunnel based on load-structure method can estimate the remaining life of in-service highway tunnels,and it is of great significance in mastering the current working state,maintaining and repairing tunnels.
