| 摘 要： | 运营隧道衬砌结构技术状况的优劣直接关系到隧道内行车和行人安全,如何对运营隧道衬砌结构技术状况进行合理评定成为人们所关注的重点.针对目前隧道工程界已有的隧道衬砌结构技术状况评定方法存在的不足,首先提出了＂隧道健康度＂和＂隧道健康度函数＂的基本概念,将检测隧道划分为若干评定单元,然后将检测数据分配于各评定单元之上,并通过隧道健康度函数,建立了隧道现场检测数据和评定结果之间的一一对应关系,建立了一种基于现场检测数据的隧道衬砌结构技术状况分段式量化评定方法,并通过工程实例验证了该评定方法的有效性.

| Abstract: | Whether the operational tunnel lining structure technical condition is good or bad is directly related to the driving safety and pedestrian safety in the tunnel. Therefore, how to assess the operational tunnel lining structure technical condition reasonably is paid close attention by people. Consider- ing the insufficiencies of existing tunnel lining technical condition assessment method in tunnel engineering circle, the conceptions of tunnel health degree and tunnel health degree function were put forward first. The tunnel was divided into several assessment units and then the inspection data were assigned to these assessment units. The one-to-one correspondence relationship between the inspection data and assessment results was established by tunnel health degree function. A segmented and quanti- fied tunnel lining technical condition assessment method based on field inspection data was put forward at last. The efficiency of the assessment method had been verified based on engineering case. |
