【摘要】 对三种不同类型材料的隧道通风进行热分析。建立隧道通风模型,通过数值模拟,分别得到其温度随时间和位移的变化规律。通过比较三种情况下隧道温度变化,可以得到采用花岗岩的隧道进出口温差最大,采用复合材料的隧道周围受空气温度影响范围最小。更多还原

【Abstract】 Analysis was carried out on the thermo analysis of tunnel ventilation in three different types of material in this paper.By setting up tunnel ventilation model, law of temperature changes could be got with time and displacement differences by numerical simulation. By comparing temperature changes under three kinds of conditions, the results showed that import and export temperature difference was biggest when building tunnel in granite whereas relatively small in compound material.更多还原
