The Deformation Control of Newly-built Shield Tunnel Passing Underneath Existing Subway Line at Close Distance
It is particularly important to take appropriate settlement control measures when a newly-built tunnel passes underneath the existing subway line at a close distance.Based on the project of a newly-built shield tunnel passing underneath the existing subway line in Jinan Metro,this paper discusses the construction precautions of the newly-built shield tunnel passing underneath the existing subway line at a close distance by numerical simulation of the construction process and combined with monitoring data and shield construction parameters,and verifies the feasibility of tunnel settlement control measures.
