长大海底道路隧道温升规律研究
Study on temperature rise laws of long and large submarine road tunnels
摘要：
依托某长大海底道路隧道,对隧道内外及岩层温度进行了测试,研究了隧道岩层温度、风速、车流量、室外环境温度等因素影响下隧道内的温升规律。结果显示:影响长大海底道路隧道内空气温度变化的主要因素为室外环境温度、车流量及岩层温度;室外环境温度对隧道进口段温度影响较大;隧道内空气温升与车流量存在一定的正相关性,但温度变化相比于车流量变化存在1～2 h的延迟。
Abstract：
This paper relies on a long and large submarine road tunnel to test the temperature inside and outside the tunnel and the rock layer temperature, and studies the temperature rise law in the tunnel under the influence of factors such as tunnel rock layer temperature, wind speed, traffic flow, and outdoor environmental temperature. The results show that the main factors affecting the change of air temperature in the long and large submarine road tunnel are outdoor environmental temperature, traffic flow and rock layer temperature. Outdoor environmental temperature has a greater impact on the temperature at the tunnel entrance. There is a certain positive correlation between the air temperature rise in the tunnel and the traffic flow, but the change in the air temperature has a delay of 1 to 2 hours compared with that in traffic flow.
