【摘要】 本文总结了在上海地铁一号线某区间隧道断面的空气温度的实测结果,分析了全天的区间隧道所测断面上的不同高度的空气温度的变化规律。结果显示:白天有列车运行的时段,中间两个测点的气温较高、两端测点的气温较低;而晚上没有列车运行的时段,气温则呈现出由上至下依次减小的规律等。通过以上规律的总结分析,对于隧道温度场的现场实测,本文分别提出了适用于短期测试的测点布置方案和适用于长期测试的测点布置方案。更多还原

【Abstract】 This paper has concluded the data of air temperature on one section of Shanghai subway tunnel,and analyzed the Change Rule of air temperature on different height in this measured section that day.The result shows that:on the train operation time during the day time,the air temperature of the second higher and the third higher measure points are higher than the result two points;while on the rest of the time,the air temperature decrease progressively from up to down...Through the analysis,this paper present the optimization of Short-term monitoring scheme and the optimization of Long-term monitoring program scheme更多还原
