Abstract
To prevent high water pressure disasters in tunnels under water-rich environments, it is necessary to study the distribution characteristics of the seepage field and optimize the waterproof-drainage system. In this paper, a series of seepage experiments and numerical simulations are conducted on the Kexuecheng tunnel in Chongqing, China. The influence of different waterproof-drainage parameters on the seepage field distribution and mechanical behavior of lining are investigated. Various optimized waterproof-drainage structural systems are proposed that are beneficial for controlling high water pressure disasters during tunnel operation. According to the results, the water pressure, lining structure stress, and water inflow of tunnel gradually increase with the increase of hydrostatic head height and longitudinal spacing of circumferential drainage tubes. Increasing the density of drainage tubes will not only enhance the drainage capacity of the tunnel, but also exacerbate the non-uniform distribution characteristics of water pressure in small interval tunnels. The maximum water pressure and tensile stress on the secondary lining are concentrated at the tunnel bottom, which is caused by the lack of drainage channels at the inverted arch and is one of the important reasons for roadbed uplift. With the increase of the distance between the two holes of small interval tunnels, the superposition effect of their seepage and stress fields weakens, leading to an increasing trend in both water inflow and lining water pressure. The six optimized waterproof-drainage schemes proposed can effectively reduce the load on the lining and increase the safety of the tunnel structure.
