Description

Technical Field

[0001] The invention belongs to the technical field of tunnel water inrush testing, and specifically relates to a tunnel water inrush testing method taking into account disaster source material deposition-high-pressure energy storage. Background Art

[0002] The occurrence of water and mud inrush disasters in karst tunnels mainly involves three parts: the source of disasters, the source channel of disasters, and the water-blocking mudstone. The source of disasters is the source power of water and mud inrush disasters. Different sources of disasters will inevitably lead to different mechanisms of water and mud inrush disasters in karst tunnels. The source of water and mud inrush disasters in karst tunnels is a complex medium system composed of one or more of solid mud, liquid karst water, and internally sealed gas. With the increase of the buried depth of the disaster source, its solid-liquid-gas three-phase mixing characteristics are more significant, and the gas sealed in the karst cavity is likely to be in a high-pressure state. When the tunnel construction approaches the high-pressure energy storage disaster source filled with a solid-liquid-gas three-phase mixture, once the safety thickness of the water-blocking mudstone between the disaster source and the tunnel is insufficient, it will rupture and become unstable, thereby losing its barrier function, inducing water and mud inrush disasters, and groundwater, mud, sand, and gas will gush out in large quantities.
