[0002] Tunnel engineering is a structure built underground or underwater or in the mountains to lay railways or build roads for motor vehicles to pass. According to their location, they can be divided into three categories: mountain tunnel engineering, underwater tunnel engineering and urban tunnel engineering. Mountain tunnel engineering is to pass under mountains or hills to shorten the distance and avoid steep slopes; underwater tunnel engineering is to pass under rivers or seabed to cross rivers or straits; urban tunnel engineering is to pass underground in cities to meet the needs of railways passing through large cities. Among these three types of tunnel engineering, mountain tunnel engineering is the most built, and tunnels are engineering buildings buried in the strata, which are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels;
