Abstract
The Tianshan Shengli Tunnel is currently the longest high-altitude highway tunnel. In order to ensure the safe operation of the tunnel, the SES software is used to investigate the wind speed laws in the tunnel, and the tunnel is divided into 16 disaster prevention sections based on the shaft and critical wind speed. The principles of disaster prevention and rescue of Tianshan Shengli Highway Tunnel are given, and the emergency treatment process of tunnel disaster prevention and rescue is given. The disaster prevention and rescue plan of Tianshan Shengli Tunnel from fire occurrence, personnel and vehicle evacuation, and fire treatment are discussed in detail.
Highlights
Highway tunnels have narrow space and limited safe evacuation exits
In order to ensure the orderly development of evacuation and rescue work, it is necessary to establish a scientific and effective disaster prevention plan
The establishment of a disaster prevention plan can reduce the casualties that may be caused by the fire, reduce property losses, and improve the operation and management level of the tunnel [3]
Summary
Highway tunnels have narrow space and limited safe evacuation exits. After a fire occurs, the fire fighting route is single, resulting in the detention of people and vehicles. Wang Mingnian et al [4] studied the disaster prevention and rescue of the Qinling Zhongnanshan Highway Tunnel and found that the fire control in the tunnel includes three parts: system linkage, traffic evacuation, and rescue and fire extinguishing. The Tianshan Shengli Highway Tunnel is located on the southwest side of Urumqi, Xinjiang. It is a two-way four-lane road with a length of more than 22km and an altitude of 2772m. Based on the characteristics of the tunnel, the disaster prevention and rescue of the Tianshan Shengli Highway Tunnel is faced with the difficulties of ventilation, smoke control, personnel escape and rescue. It is necessary to conduct an in-depth study on the disaster prevention zone and rescue plan of the Tianshan Shengli Tunnel to provide reference for the disaster prevention and rescue design of the tunnel
