摘　　要：随着公路建设工作的开展,越来越多的隧道投入使用,作为地下建筑,施工较为复杂且难以对隧道进行全面检查,如难以对二次衬砌厚度进行全面检查。隧道通车一段时间后,在自然作用下,容易在拱墙背后出现空洞,无论是二次衬砌厚度不足还是拱墙背后出现空洞,在水的作用下,都极其容易引发多种隧道病害,如渗水病害。在发生渗水病害后,应第一时间对渗水部位进行处理,最常用的处理方法就是注浆封闭,将拱部背后空洞进行填充,能很好的治理隧道渗水病害。With the development of highway construction work,more and more tunnels are being put into use.As underground buildings,the construction is more complex and it is difficult to comprehensively inspect the tunnels,such as the thickness of the secondary lining.After the tunnel is opened for a period of time,under natural action,it is easy to have voids behind the arch wall.Whether it is insufficient thickness of the secondary lining or voids behind the arch wall,under the action of water,it is extremely easy to cause various tunnel diseases,such as seepage diseases.After the occurrence of seepage disease,the seepage area should be treated as soon as possible.The most commonly used treatment method is grouting sealing,filling the cavity behind the arch,which can effectively treat the tunnel seepage disease.
