A pressure fluctuation is generated when a high-speed train passing through a tunnel, and we need to take its load pressure into account in the structural design of tunnel lining. The maglev train of the Linear Chuo Shinkansen will travel at a speed of 500km/h and it is required to consider the abnormal loads caused by aerodynamic brake system function when an abnormality occurs. In this study pressure is measured when a train runs into and runs through the tunnel of the Yamanashi Test Line and numerical simulations of flow around maglev trains passing by each other are conducted to evaluate the maximum loads on a tunnel lining when the aerodynamic brake system is activated. The stress versus the maximum loads under operation trains conditions is examined by simulating the stress for a tunnel lining by FEM.
