A General Framework for the Impact of Shield Tunnel Construction on Existing Tunnel in Soil

During the excavation process of shield tunneling, it is inevitable that surrounding soil mass disturbed, which will affect adjacent structures. This paper proposes a general framework for impact tunneling construction on existing tunnels. First, partition regarding tunnels and buildings established by three-dimensional numerical analysis method. Then, displacement predicted using fuzzy gray theory. Finally, based results simulation experiment, risk classification standard established. has certain reference significance value deformation prediction safety evaluation buildings.
