In recent years, the construction of urban tunnels in China is accelerated, and particularly in large and medium cities with shortage of land resources, the urban tunnels effectively improve the utilization rate of soil and reduce environmental pollution. For urban tunnels, the high-speed, low-energy-consumption, safe and efficient operation of motor vehicles in the tunnels is also the advocate according with the current low-carbon life. In consideration of the diversity of the use functions and the particularity of the geographic positions, the urban tunnel has some remarkable characteristics, the limitation of the terrain, the urban planning land and the existing building (building), and the use requirements of the existing line and ground building, so that the urban tunnel faces a plurality of challenges during construction, operation and maintenance. After statistics is carried out on 57 tunnels with safety problems in primary support in the construction period of China, the fact that except the construction quality problem caused by human factors, the influence of water damage problems (underground water, rainfall and the like) on the safety of tunnel engineering is the most common is found, and the safety problem caused by the underground water accounts for 58% of the total number of the tunnels. Once water problems occur in the tunnel, a large amount of groundwater loss outside the tunnel, the underground water level reduction, the surface water source exhaustion and the like can be caused, and the water loss and soil erosion, the vegetation damage, the ground collapse and the like can be caused. The problem of solving the tunnel water is beneficial to the safety of the tunnel structure, prolonging the service life of the tunnel structure and protecting the surrounding ecological environment, and becomes a key factor influencing the success or failure of the tunnel engineering.
At present, urban tunnels in China mainly adopt 3 waterproof and drainage systems: 1) a drainage type or drainage self-drainage type system mainly comprising drainage and drainage is adopted, and the water pressure behind the lining is reduced by reducing the underground water level behind the lining, but the method easily causes uncontrollable reduction of the underground water level, influences surface vegetation and damages the environment; 2) the full-covered waterproof system isolates the stratum seepage water outside the secondary lining of the tunnel, and improves the waterproof capability of the composite lining, but the method can increase the water pressure load borne by the tunnel structure and is unfavorable for the long-term operation of the urban tunnel; 3) the control type waterproof system combining prevention and drainage usually adopts a half-pack waterproof mode, allows partial drainage of underground water, can ensure the structural safety and can reduce the water pressure at the back of a lining, but the method is difficult to master the balance of the water pressure and the drainage quantity. Above 3 kinds of urban tunnel prevent drainage mode all have certain drawback, prevent that the displacement is difficult to control, consequently need an intelligent urban tunnel prevent drainage system.
The field of tunnel engineering generally considers that the BIM technology becomes an important technical support for information-based construction, is an important mark for urban tunnel operation management, and is a mainstream trend for future development.
