Abstract

The invention discloses a water-rich fault tunnel face water inrush evolution simulation test device and method, and belongs to the field of underground construction engineering simulation. The water-rich fault tunnel face water inrush evolution simulation test device comprises a water pressure loading system, a simulation box body, simulation soil layers laid in the simulation box body in a layered mode, an information monitoring system and a simulation tunnel excavation system. The water pressure loading system firstly adds water into a pressurizing tank and then injects air to achieve a pressure maintaining effect, and constant pressure stability of the information monitoring system is guaranteed; and the information monitoring system comprises a plurality of stress monitoring points, and the stress monitoring points are evenly distributed around the simulated fault and the simulated tunnel and used for monitoring the dynamic deformation process. The device is used for simulating the conversion process among the thicknesses of the disturbance failure zone, the effective water insulation zone, the induced fault zone and the fault failure zone. Multi-field coupling of a stress field, a seepage field, a displacement field and the like in the tunnel water inrush process can be obtained, and mechanical characteristics and evolution laws in the tunnel rock mass structure progressive failure process are disclosed.

Description

technical field [0001] The invention relates to the field of underground construction engineering simulation, in particular to a simulation test device for water inrush evolution at the tunnel face of a water-rich fault tunnel. Background technique [0002] When the tunnel construction encounters loose and broken rock mass, the stability decreases, the surrounding rock deforms and cracks, and a large number of cracks are formed, which induces geological disasters such as water gushing and landslides. Water and mud inrush is a major geological disaster often encountered in the construction of deep and long tunnels, accounting for about 40% of all kinds of disasters. The breeding and evolution mechanism of tunnel water and mud inrush disasters is not clear enough, which leads to more and more serious tunnel water and mud inrush disasters. The main reason is that currently there is a lack of corresponding three-dimensional experimental simulation devices for simulating the dyn...
