Finite Element Method Analysis of Influence on Subway Tunnel Adjacent to Excavation by Excavation Construction
The interaction influence on subway tunnels adjacent to foundation excavation was produced by excavation construction, and it is great significance for the correct assessment of its size and influence on the safety of subway operation. Based on the foundation excavation project, some typical foundation excavation profiles are selected, the calculation and analysis on additional settlement and h...
متن کاملCross Section Effects on Convergence-Confinement Method in Multi Stage Tunnel Excavation
Dimensionless coefficient () in convergence confinement method shows the relaxation of stress in the wall of the tunnel at different excavation movements. This factor is considered a constant number in previous studies and tunnel geometric characteristics (such as depth, cross-section shape, radius, soil material, etc.) are not included in its determination; however, ignoring these effects can...
متن کاملOn the selection of an appropriate excavation pattern for urban tunnels with big cross-section: A case study
Among various practical measures used for restriction of the ground surface settlement in such tunnels driven in soft ground, selection of an appropriate excavation method plays a significant role. In this paper, employing suggested diagram by Yu & Chern, corresponding values of Niayesh tunnel has been inserted into the diagram. Later, two excavation methods namely: central diaphragm and side d...
متن کاملInfluence of Underground Excavation of Large-Section Intercity Railway Tunnel on Adjacent Pile Foundation
Three-dimensional model is established with finite difference method to simulate construction process based on design and construction plans of existing overpass pile foundation adjacent to certain large-section railway tunnel in Chengdu, China. Ground, isolation pile, main bridge pier and ramp pile near the tunnel are taken as research object, and surface settlement amount, displacement change...
متن کاملNumerical Investigation on Effects of Deep Excavations’ Position on Existing Metro Tunnels in Urban Areas
Nowadays deep excavations are needed for construction of foundation of high rise buildings, providing space for parking and etc. In some cases deep excavations may be constructed in the vicinity of the subway tunnels and causes unpredicted extra displacements and internal forces in tunnel lining of tunnels which were not designed for them and consequently affect serviceability of tunnel. Theref...
