“…Proposed a structural form suitable for high water level tunnel and the structural form of controlled drainage scheme, and studied the water pressure distribution in the tunnel lining by theoretical analysis, indoor tests and eld measurements [19]. Developed an assessment framework based on a regionally coupled hydrological model to study the effects of tunnel drainage on surrounding vegetation [20][21][22][23]. However, the current research results of tunnel drainage prevention are conventional drainage methods.…”

For the water-rich area tunnel elevation arch in the high-water pressure often causes elevation arch cracking and leakage, bulging and other disasters. When the drainage system is not designed properly, such disasters occur more frequently, and conventional road tunnel drainage cannot effectively reduce the water pressure at the elevation arch. Therefore, this paper proposes a new concept of "three-way drainage". The three-way drainage system is based on the conventional drainage system with a new drainage inlet at the elevation arch. On this basis, a series of numerical simulation studies are conducted to verify the pressure-reducing performance of the three-way drainage system on the lining. After demonstration and analysis, the three-way drainage concept can not only effectively reduce the water pressure at the elevation arch of the tunnel, but also have a significant effect on the overall drainage effect of the tunnel. The factors affecting the performance of the three-way drainage system are discussed by varying the model parameters. It was found that the hydraulic conduction coefficient of the surrounding rock and initial support, the number of reverse diversion holes in the elevation arch, the change in head height and the change in secondary lining parameters all had a significant effect on the water pressure outside the tunnel.
