Due to the particularity of the urban tunnel, the presence of buildings and vegetation on the ground makes the urban tunnel face a lot of challenges during operation and maintenance. After field investigation is carried out on a large number of urban tunnels in China, the construction quality problems caused by human factors are found to be the most common, and the water damage problems (underground water, rainfall and the like) have the most common influence on the safety of tunnel engineering, and the safety problems caused by the underground water account for 58 percent of the total number of the tunnels. When the urban tunnel has a water hazard problem, the underground water level is generally reduced, so that surface water sources are exhausted, water and soil loss, vegetation damage, ground subsidence and the like occur. The method can effectively prolong the service life of the urban tunnel and has positive effect on the surrounding ecological environment by solving the problem of tunnel water, and becomes a key factor influencing the success or failure of tunnel engineering.
