运营老旧铁路隧道病害检测与分析研究

Disease Detection and Analysis of the Old Railway Tunnel in Operation Period

当前我国隧道工程正在由建设期转入运营期,越来越多的隧道即将进入服役阶段,对于运营多年的老旧铁路隧道,病害问题尤为突出。以成渝铁路某隧道为例,通过地质雷达、裂缝检测仪等无损检测仪器对隧道病害进行检测,从外观病害、地质雷达检测结果、水样成分分析角度对隧道病害展开研究。在此基础上,从工程水文地质、设计与施工理念、运营维护、病害关联性方面对老旧病害隧道病害原因进行分析。

Nowadays,China’s tunnel construction is from the construction period into the operation period,more and more tunnels are about to enter the service stage,the disease is particularly prominent for the old railway tunnel in operation peri-od for many years.This paper takes a tunnel of Chengdu-Chongqing Railway as an example to detect the tunnel disease through nondestructive detection instruments such as geological radar and the crack detector.A research is carried out on tunnel diseases from the angles of the appearance of the disease,the detection results of geological radar results and the wa-ter component analysis.On this basis,the paper analyzes the causes of the tunnel diseases in terms of the engineering hydrologic geology,the concept of design and construction,the operation maintenance and the disease association.
