Surface subsidence is one of the key control indexes of tunnel construction. Peck formula is generally adopted to estimate the settlement of the soft ground induced by shallow tunneling work, which is suggested by Professor Peck in 1969. Verification work is necessary to be done before the formula is applied in engineering. At present, the application experience of Peck formula in Quasi-rectang…

The structure of a segmental joint with a load-transferring gasket is complicated and exhibits piecewise and nonlinear deformation characteristics under loads. Joint stiffness largely depends on the properties of the concrete and load-transferring gasket, which are the main components of the joint. A reasonable consideration of their influence is one way to predict the failure process of the …
The cutter ring breakage as a cutter failure mode in shield tunnel construction is more likely to occur in the centre zone of cutterhead. Given the inconsistence of this phenomenon with the linear cutting theory, the present paper suggests the use of the circular cutting theory to explain the cutter ring breakage and find the correlation between the unbalanced side force and cutter ring breakag…
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…
