| 摘 要： | 为确定公路隧道内路面结构温度变化规律,提供隧道路面工作环境温度指标,利用有限元方法对隧道空气温度分布状况进行预估.结果表明长、短公路隧道中部空气温度呈现出不同分布状态:短隧道中部空气温度受洞外气温影响较大,表现出与洞外相同的变化趋势;采用纵向机械通风的长隧道中部空气温度一年中趋于稳定;隧道进出口处温度受洞外空气状况影响强烈.分析结果能够为隧道内路面结构设计和材料选择提供理论依据和指导作用.

| Abstract: | In order to define pavement temperature field distribution inside highway tunnels and offer temperature index of pavement working environment,the finite element method (FEM) was developed to calculate the temperature field of air in highway tunnel. The result shows different regularities:air temperature in the middle of the short tunnel is affected strongly and represents the uniform trend as the outside tunnel,but that of the long tunnel equipped with lognitudinal ventilator is a fixed value. Otherwise the... |
