and the geometry model in dealing with the factual problems. Only the numerical method (such as the finite element method and finite difference method) is used to resolve it. The flow conductance S is a key... models was performed after analyzing data available because material behavior influenced the choice of the proper viscosity model to use for numerical simulations. The material viscosity (Fig.1) quickly......

during the excavation of long-distance single ended tunnel, the full-scale physical model of working face was established by using FLUENT software, and the numerical simulation analysis of tunnel... Establishment of geometrical model In order to achieve the effect of numerical simulation to reflect the actual situation on the site, a scaled physical model was established by SOLIDWORKS. As shown in Figure......
Establishment of finite element numerical simulation model 2.3.1 Subroutine UMAT ABAQUS is a powerful finite element software for engineering simulation, whose solutions range from relatively simple... to previous studies [27-32], the range of influence of the vibration wheel in the horizontal direction during compaction is about 5 m, so the length and width of the numerical model are each 10 m......
to Nanning City) in southwest of China. A full-scale model of earth embankment was established by means of numerical simulation with FLAC3D code. The numerical results were verified by shaking table.... The full-scale analysis model can be established, and the imposed load can be changed or repeated as expected in numerical analysis. Consequently, the numerical analysis method is widely taken for extensive......
