Description

Technical Field

[0001] The present invention relates to the technical field of dangerous rock masses, and in particular to a simulation device for multi-scenario dangerous rock collapse tests and a method for using the same. Background Art

[0002] Collapse refers to the geological phenomenon in which rock, soil or debris on a steep slope suddenly separates from the parent body due to gravity and rapidly falls, rolls or accumulates. Dangerous rock collapse refers to the sudden instability and destruction of the rock-soil complex on a steep rock slope along the dominant structural surface under the coupling of self-weight stress, seismic load, precipitation infiltration and external forces, causing the block to separate from the parent body and migrate to the foot of the slope through multi-modal dynamic processes such as toppling, shear slip, free fall and collision rolling, eventually forming a type of surface geological disaster with disordered accumulation. Among them, dangerous rock refers specifically to the rock mass on a steep slope that exhibits time-dependent deformation characteristics such as structural surface expansion, displacement monitoring anomalies or fissure seepage due to structural surface degradation, stress field adjustment or changes in hydrological conditions, and is a rock and soil unit (i.e., potential collapse source material) with the potential for instability and destruction.

[0003] Many factors can cause landslides, including earthquakes, precipitation and snowfall, surface erosion and soaking, and irrational human activities. Atmospheric precipitation events, through the coupling mechanism of transient pore water pressure surges and attenuated rock matrix suction, can cause structural deterioration (weakening cohesion and decreasing internal friction angles) in the rock mass. This leads to a progressive expansion of the dominant structural plane, ultimately resulting in sudden instability from a critically stable state. Given that the mechanism of landslide disasters involves complex multi-field coupling mechanisms and is limited by the spatiotemporal resolution of in-situ monitoring technology, current research relies on multi-physics coupling test platforms (such as rainfall-vibration-seepage composite simulation systems) to construct scaled models of similar geomechanical materials to conduct quantitative inversion of rock mass instability processes and determine catastrophic thresholds.
