摘　　要：在铁路隧道施工中,由于地质条件和施工因素,在隧道混凝土衬砌施工完成后,富水量大的地段会出现混凝土渗水情况,隧道混凝土渗水将影响工程验收和后期使用运行,处理隧道衬砌渗水是一个不能避免的过程。隧道渗水处理一般采用化学性灌浆材料进行化学灌浆防渗漏,化学灌浆材料在遇到水后发生化学反应,从而形成弹性胶状固结体,使渗水部位达到很好的止水目的,达到防水止漏效果。Due to geological conditions and construction factors,concrete seepage will occur in the section with large water content after completion of tunnel concrete lining construction.The seepage of tunnel concrete will affect the acceptance and later operation of the project.It is an unavoidable process to treat the seepage of tunnel lining.Chemical grouting material is generally used in tunnel seepage water treatment to prevent seepage.Chemical grouting material reacts chemically after encountering water,thus forming elastic gum-like consolidation,so that the seepage area can achieve a good water-proof effect.
