The friction between the tires of the vehicle and the road surface can be reduced due to the icy road surface, the control of the vehicle on the direction and the brake is greatly influenced, and major traffic accidents are often caused.
In winter, the tunnel portal is a road section which is very easy to freeze, and the reasons are as follows:
1. in winter, snowfall weather often occurs, the hillside above the tunnel portal is easy to accumulate snow, water flow formed when the snow is melted flows down to the tunnel portal along the hillside, and ice blocks are formed at the tunnel portal when the temperature is reduced.
2. The tunnel is generally warm in winter and cool in summer, air can be driven to flow by the passing of vehicles, the temperature in the tunnel is higher than that of air outside the tunnel, and at the moment, the air flow outside the tunnel is in contact with the air flow in the tunnel to form condensed water at the opening of the tunnel, so that the tunnel is very easy to freeze.
3. Some tunnels may be built in places where groundwater is abundant and buried shallow, and are prone to groundwater seepage and freezing due to low temperature when groundwater flows through the opening.
4. When a vehicle brakes before entering a tunnel, the vehicle body may spray water to the brake pot, and water drops to the tunnel mouth to form ice blocks. When the tunnel mouth freezes, the driver brakes at the place and easily causes the vehicle out of control, especially in places such as highway and the like where the vehicle speed is fast, brakes before entering the tunnel, and the vehicle speed suddenly reduces and may collide the tunnel wall or rear-end collision occurs and the like, thereby causing major traffic accidents.
