Abstract:

Ground movements caused by the tunnel construction in soft ground endanger the safety of the existing building.Double control criterion was proposed for shield tunnel undercrossing by taking the existing deformation of building into consideration.For Shanghai Metro Line 11 undercrossed the Chongsi Building,Xuhui Middle School,the deformation of Chongsi Building was detected and analyzed,and the status of the building was assessed.The double control criterion for shield tunnel undercrossing Chongsilou Building was established based on a consideration of the building existing deformation.A management over the section undercrossing the Chongsi Building proves the feasibility of the deformation control criterion.

Key words:shield tunnel; undercrossing; disturbance; existing deformation of building; double control criterion
