公路隧道常见病害及防治措施研究

The Research on the Common Diseases and Preventive and Control Measures of Highway Tunnel

隧道病害是长期困扰我国交通运输事业可持续发展的关键问题。针对国道307、省道315、阳泉天子庙隧道中存在的隧道衬砌结构开裂、隧道水害、衬砌腐蚀、衬砌结构背后空洞和不密实等病害,分析其产生原因及致灾后果。提出了隧道病害的预防措施,从而提高衬砌结构的承载力、围岩自稳性、底板稳定性等。针对隧道不同的病害类型,提出了相应的处治措施,预防与治理相结合,对提高公路隧道安全性有积极意义。

For the tunnel lining structure crack, tunnel water disasters, lining corrosion, cavity and non-compaction of the lining structure, this paper analyzed the causes and the consequences of the disasters, put forward the preventive measures of the tunnel diseases, which improved the bearing capacity of the lining structure, the stability of surrounding rock and the bottom slab,etc. In view of the different tunnel disease types, it also put forward the corresponding treatment measures that combined the prevention with treatment, which had a positive significance to improve the safety of highway tunnel.
