subway tunnel
5.Exercise the regulation of the train was compiled the procedure of UDF in C language . Thirdly, the piston wind was simulated in the subway zone tunnel, compare the numerical results with theory calculation and measure, the rationality of physics mathematics model and the method of computation were validated.
8.Unifies the seismic damage performance of the kobe subway in the great han shin earthquake of japan,this article has analyzed the seismic damage characteristic of the city subway station and the sector tunnel,and discussed the seismic damage mechanism of the metro engineering,finally proposed the countermeasures for reducing seismic damage in the subway line plan stage,the aseismic design stage and the subway construction stage.
