活塞风对寒区高铁隧道衬砌结构传热影响分析
Effects of piston action on heat transfer in lining structures of high-speed railway tunnels in cold regions
摘要
Abstract
Considering the frequent frost damage issues in cold-region high-speed railway tunnels,this study com-bined on-site monitoring data from the tunnel site to simulate and analyze the heat transfer process between the in-side and outside air and the tunnel structure under the scenario of two trains passing in opposite directions on the coldest day.Furthermore,the effects of train speed(80～250 km/h)and external air temperature(-4℃ to-30℃)on the structural layers and heat transfer process inside the tunnel were investigated.The conclusions are as follows:the air temperature inside the tunnel and the temperature within the structural layers are symmetrically distributed along the longitudinal direction throughout the tunnel.Moreover,the temperature is relatively lower at both ends of the tunnel,and the piston wind does not affect the distribution of air temperature or the temperature in-side the tunnel's structural layers.However,the outside air temperature and train speed greatly influence the air temperature near the tunnel entrance and the internal temperature of the secondary lining.Specifically,as the out-side air temperature decreases and train speed increases,the drop in temperature within the tunnel and the second-ary lining becomes more pronounced.The main influence range of outside air temperature extends up to 500 m from the tunnel entrance,whereas the maximum longitudinal impact of train speed on the temperature within the structur-al layers can reach up to 1 000 m.关键词
