Abstract
The impermeability of concrete of the exterior wall of the underground tunnel in water-rich stratum is a key concern of engineers. Taking the Aixihu highway tunnel in Nanchang city as an example, the impermeability of the concrete in the side wall of the highway tunnel is tested, through multiple tests, such as the embedded steel pipe, water injection, and field observation. The results show that, under the action of 2mpa of water pressure, no water flow permeates from the side wall of the concrete tunnel, indicating that the impermeable performance of concrete tunnel in this section meets the engineering requirements, and hoping that this research can be used as a reference for other similar projects.
