Two centrifuge model tests with different vertical clearances were carried out to investigate the new shield tunneling on an existing overlying large-diameter tunnel. The difference of the two centrifuge model tests lies in different vertical clearance between the two tunnels. Two construction steps of a new shield tunnel were simulated in the test. The vertical displacement and the longitudina…

DOT has the characteristics of special section and relatively large area of excavation face. Its propulsion will cause large formation disturbance. But too much soil disturbance usually leads to a series of environmental diseases. 3D elastoplastic FDM model was applied to analysis the dynamic construction process relying on a DOT project in Shanghai. Surface displacement field and the distrib…
Nowadays the problem of soil loss during construction of shield driving has attracted much attention, especially in sandy silt. Moreover, it is easy to cause ground subsidence and destruction of surrounding environment because of the soil’s sensitivity and disturbing characteristic. Factually, existing tunnel has high control standards for deformation as well as its deformation occurs easil…
