The effect of CRD method and auxiliary construction on surface settlement in shallow-buried tunnels
Several engineering practices have shown that the excavation of shallow-buried tunnels beneath major roads, as well as the selection of appropriate engineering measures and construction methods, has a significant impact on road surface settlement ...

Influence of large diameter deep buried pipe jacking construction on surface settlement
Pipe jacking construction is widely used in urban construction due to non-excavation or less excavation, but the surface settlement caused by pipe jacking construction cannot be ignored. Relying on a pipe jacking project of a power tunnel in Foshan City,

A Numerical Study of the Effect of Tunneling on Surface Settlement and Existing Buildings [PDF]
This study aimed to determine the effect of various influencing parameters such as tunnel diameter (D), depth (H), width (B), length (L), number of floors, and the horizontal distance of the building from the tunnel axis (X), as well as soil properties such as internal friction angle (ϕ), Poisson ratio (υ), modulus of elasticity (E), and cohesion (C ...

A New Modified Peck Formula for Predicting the Surface Settlement Based on Stochastic Medium Theory
Peck method and stochastic medium method are the two most commonly used methods to estimate surface settlement caused by tunnel excavation. However, the Peck method was not suitable for a shallow-buried tunnel, and the calculation process of the ...

Surface Settlement of Deep Foundation Pit Considering the Influence of Excavation and Freeze–Thaw
In order to address the issue of surface deformation in wintering foundation pits in seasonal frozen soil areas due to excavation and freeze–thaw, an indoor scale model test was conducted to examine the displacement relationship between pit wall soil and
