Abstract:An introduction is given to strengthening of tracks with shallow-buried tunnel going through under it in sandy silt stratum. D24 auxiliary beam was used for track strengthening, and dewatering measures were adopted at sandy silt stratum, and long pipe roof was used for tunnel support. Grout injection and CRD construction method was used to ensure operation safety.
Keywords:existing railway  urban tunnel  construction
