Název v původním jazyce

Numerical simulation for horizontal tunnels with vertical alignment affected by static and dynamic loads

Popis výsledku v původním jazyce

Most of the researchers are constructed twin tunnels as horizontal, in some cases the twin tunnel vertically overlapping lined horizontal tunnels are constructed in order to avoid the other structure as like pile foundations. This paper illustrates the 3D numerical model by using software MIDAS GTS NX which is established to investigate the tunnel simulation in order to highlight the effect of static and dynamic load on the behaviour of tunnel lining. There are several points which have effect on the results of design as like distance between the two tunnels, the stiffness and density of the lining material and ground, the character and magnitude of seismic loading, etc. Inner diameter of analysed tunnel is marked of D = 6 m. Thickness of concrete lining corresponds of t = 0.3 m. The depth of the top part of tunnel from the ground level is of 10D m below the surface of the ground. Distance of the twin tunnel centres is of 3D m. Response Spectrum of UBC (1997) is used as seismic response spectrum, were undertaken to compare the results in the displacement and stresses acting on the grouting/segment to find the quantity of deformation through tunnelling, finally to approve that the applied dynamic stress is not negligible for underground structure, but it is less dangerous in comparison with the others.
