Investigation on the Dynamic Response of a High-Speed Railway Tunnel Located Beneath an Airport Runwdes of transport. Some modern integrated transport hubs have been operated, and at least 32 airports in China are planning to combine air transportation with high-speed railway transportation. To realize the “seamless transfer” between the airport and the high-speed railway station, some high-speed

Dynamic Response and Long-Term Settlement of Four Overlapping Tunnels Subject to Train Loadhe tunnel structure can be threatened a lot by complicated dynamic response of tunnel–ground system under train load, especially in the overlapping cases. Based on a case of four overlapping tunnels in soft clay region, dynamic response of the tunnel–ground system and long-term settlement of the tun

Research on Calculating Quantity of Utility Tunnel with Revit Secondary Developmentwever, the process for quantity calculation based on the design model from the utility tunnel is inefficient because of the inaccurate recognition. Issues in quantity calculation will be resolved with the method related to Revit secondary development (RSD) proposed in the paper. On the basis of Appl

The Influence of Variation in Groundwater Table on Ground Vibrations from Underground TunnelsThe saturated porous medium is used to model the soil layer under the groundwater table, and the dry single-phase medium is applied to simulate the soil above the groundwater table. The transfer matrix method and wave transformation are applied to derive the solution for a tunnel in a dry/saturated

Dynamic Response of Floating Slab Track with Variation on Failure Position of Steel Springof floating slab track, the damage or failure of the steel spring is inevitable, which will have a bad effect on the track dynamics and vibration-mitigating effects. The steel spring’s forces were calculated by the vertical coupled dynamics model for the metro and the floating slab track. The dynami

The Effect of Boundary Permeability on the Dynamic Response of the Layered Saturated Ground Subjecteed analytically. The tunnel is modeled by an Euler–Bernoulli beam located between two horizontal layers. The Biot’s dynamic equations for the poroelastic soil medium are solved by utilizing the Helmholtz decomposition and Fourier transformation. Combining the boundary conditions and the continuity c

The Effect of Excavation Unloading on the Deformation of Existing Underlying Shield Tunnelf the tunnels due to the above unloading. The investigation showed that (1) tunnel may be uplifted owing to the above excavation; (2) the deformation of the tunnel section due to above unloading exhibits vertical elongation and horizontal shortening, and the transversal shape of the tunnel changes f
