Numerical Analysis of Wind Pressure at Subway Tunnel Platform Screen Door

Abstract

In this paper, the calculation method of numerical simulation of compressible viscous flow field is used to establish the two-dimensional subway train and tunnel model. The wind pressure change of the piston is realized when the subway train passes through the platform at different speed grades. This paper mainly analyzes the distribution law of the wind pressure in the direction of the train running, and provides the wind pressure load data for the structural design of the shield door structure, and puts forward the recommended value of the pressure of the subway shield door when the train is running at 120km/h, To prevent the wind pressure on the shield door structure damage.
