Abstract:A series of model tests were performed to investigate the load-bearing mechanism of a mined railway tunnel lining under water pressure. To investigate the load-bearing characteristics of different types of linings, a fully closed water pressure exerting device for a noncircular section tunnel was invented. A large-scale model test (1:30) under combined water and soil pressures was conducted to investigate the mechanical characteristics, deformation, stress distribution, crack development process, and failure m… Show more
“…To investigate the load-bearing mechanism of underwater mined-tunnel linings, some model tests were performed, employing an equivalent water loading device and a surrounding rock-pressure complex loading device [12]. The progressive failure characteristics for the waterproof and drainage types of lining structures were observed and analyzed, indicating that the waterproof lining has a higher water-pressure resistance than the drainage lining.…”
