제안 방법
- 1. Train-induced vibrating load was calculated by a few parameters such as design velocity, velocity impact factor, i, axial load of a train, and trackbed pressure with sine equation, accordingly, a sinusoidal shape of loading were obtained and applied to the analysis.
- In the first stage, soil must reach the static equilibrium which represents the initial in-situ stress conditions. Therefore, a static analysis was conducted based on the material properties and static boundary conditions.
- (2008) have used the coupled periodic finite element-boundary element approach for predicting vibrations due to subway traffic in Beijing. This model exploits the invariance or periodicity of the system in the longitudinal direction using the Fourier or the Floquet transform to formulate the problem in the frequency-wave number domain.
대상 데이터
- 1 describes the generated grid of 3D model and tunnel. The model size was 100 m in width, 200 m in length and 66.8 m in depth. The buried depth of the tunnel was 12.
이론/모형
- In order to analyze the dynamic behaviors of shield tunnel, a 3 dimensional model was built based on a dynamic finite difference method.
- In this study, a finite difference method was used to investigate the effect of train-induced vibration on the circumjacent soil. Especially, the liquefaction potential due to the propagation of the traffic vibration was analyzed by the numerical analysis.
- (2014) examined the seismic response of the fluid-structure interaction (FSI) of an undersea tunnel in a broken fault zone during a bidirectional earthquake. The FSI model was created by the finite element method to account for the effects of seepage, dynamic liquid pressure, viscoelastic artificial boundary. The time dependent displacement and acceleration of tunnel structures were obtained and monitored during the earthquake.
- The behavior of the generated 3-D model was assumed to be subjected to the elasto-perfectly plastic constitutive equations in the Mohr-Coulomb criterion. Thus, the Mohr-Coulomb model was adopted to perform the static analysis.
