高速铁路双线隧道列车风特性与人员安全性分析
Characteristics of Train Wind and Analyses of Personnel Security in High-Speed Railway Double-Line Tunnel
摘要
Abstract
According to the three-dimensional incompressible Navier-Stokes equations and the standard turbulence model,the 100 double-line tunnel cross-section which is generally used in high-speed railway of China is studied,this paper has made a thorough study on the variation rules and distribution characteristics of train wind,and has calculated the maximum wind speed at different positions on the two evacuation passageways,at the same time the influence that train wind on personnel safety is further discussed.The results show that:Train wind is complex three-dimensional flow which is changed with time and space,person should avoid activities at dangerous time,personnel safety may be threatened by train wind on two train driving conditions:one is that a single train runs through tunnel normally while the other is that another train runs beside a train parked in the tunnel.Corresponding measures should be taken to avoid accidents.关键词
