| Abstract: | Taking into consideration of right track construction in shield excavation of Phase I test section on Lanzhou line 1, the paper discusses the settlement control during shield excavation. The construction takes monitoring measures, backfill grouting and surface grouting and other technical measures to ensure smooth advance of shield tunneling in water-rich sand and gravel stratum, to reduce surface and pipeline settlement and improve quality of tunnel construction. |
