Abstract: Against the construction safety of super-shallow buried and water-rich subway transverse channel, laboratory experiments, theoretical analysis and numerical simulation were conducted to select the proper grouting parameter and excavation method, and a series of grouting and excavation method were put forward. Grouting reinforcement could effectively improve the mechanical parameters of sand layer and mechanical properties of soil. The later the support time was, the greater deformation of surrounding rock would be. Pre-reinforcement could effectively improve the physical and mechanical parameters of surrounding rock, reduce the deformation of surrounding rock, and improve the stress-strain relationship. Vault settlement, stress and plastic zone distribution characteristics analysis of excavation step method and CRD(Cross Diaphragm)method were compared, and feasibility of the method was determined. The research results could provide certain references to similar projects.

Key words: undercutting method, super-shallow buried and water-rich sand stratum, numerical simulation, grouting reinforcement, excavation stability
