Explanation of tunnel climate terms

Tunnel climate refers to the comprehensive action state of temperature, humidity and velocity of tunnel air.

Data expansion:

The most basic parameters are temperature and humidity, which can reflect the climate conditions inside the tunnel. When the weather is hot in summer, the temperature in the tunnel will rise abnormally, which will easily lead to traffic accidents. At the same time, abnormal humidity will also lead to slippery roads, and even lead to icing inside the tunnel, which will also pose a major threat to traffic safety.

In addition, tunnel meteorological monitoring also needs to detect air quality and atmospheric pressure. Due to the large traffic flow and emissions in the tunnel, the air quality will also be problematic. Too noisy tunnel environment and sudden change of atmospheric pressure may lead to dizziness and other physical discomfort of drivers, which may lead to traffic accidents.

The main purpose of tunnel meteorological monitoring is to improve traffic safety. By monitoring the relevant meteorological parameters, we can timely warn and control the dangerous factors in the tunnel, the entrance and exit and the surrounding areas, and ensure the traffic and travel safety.

Tunnel introduction:

Tunnel is an engineering building buried in the stratum, and it is a form of human using underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels and military tunnels. The tunnel conference held by the Organization for International Economic Cooperation and Development in 1970 integrated various factors, and defined the tunnel as: "A cave with a cross-sectional area of more than 2 square meters, which was built underground for a certain purpose and in accordance with the specified shape and size by any method."

Qinling Zhong Nanshan Highway Tunnel:

The longest two-hole one-way highway tunnel in the world. It starts from Qingcha, Chang 'an District, Xi in the north and reaches Yingpan Town, Zhashui County, Shangluo City in the south, with a total length of 18.02km and a design speed of 80km/h. People can drive 15min to cross the Qinling Mountains, the north-south dividing line in China.

This "world's best" was completely designed and built by China people, and the design also embodies the concept of humanization: special lighting belts are specially set in the tunnel, and different lights and slide patterns change to show scenes such as "blue sky", "white clouds" and "rainbow", which can make drivers and passengers feel like they are outdoors and help alleviate the fatigue of driving and riding.
