In view of the technical problems of water inrush and flooding in shaft No.1 of Gaoligongs-han Tunnel of Darui Railway,the causes of water inrush and flooding in structural fracture zone in shaft construction were discussed through hydrogeological analysis and field test.The comprehensive treatment technology of"composite cement slurry water stop pad+targeted grouting"was adopted to solve the water inrush problem in shaft construction and restore the function of flooded shaft.The re-search results can provide technical reference for similar projects.
