Abstract:Relying on a utility tunnel project constructed by the ultra-small clear distance shallow buried-tunneling method in Shenzhen, a three-dimensional numerical mechanical model is established to study the deformation and stability of soil body and structure under the different control conditions, and to explore the key design and construction measures of shallow buried-tunneling method under the close working conditions. Its contents mainly include the methods of groundwater control, stratum pre-reinforcement technology, advance pipe shed pre-support and excavation by steps.
Keywords:ultra-small clear distance   shallow buried-tunneling method   pipe shed   excavation by steps
