A device and method for simulating gradual slope change and groundwater inrush.

Abstract

This invention relates to the field of slope simulation testing technology, specifically to a slope gradient and groundwater spur migration simulation device and method. The slope gradient and groundwater spur migration simulation device includes a base system, a simulation coupling unit, and a drive actuator. The simulation coupling unit includes a slope simulation component slidably mounted on a vibration generator base. The vibration generator base is configured to synchronously drive the slope simulation component to generate vertical vibration excitation and horizontal displacement. When the slope simulation component approaches a static fixed base during horizontal displacement, the drive actuator forces the slope simulation component to rotate through contraction, achieving a dynamic gradient change in the slope of the slope simulation component from an initial gentle state to a steep state. This solves the technical problem that existing testing devices cannot synchronously couple slope movement under seismic vibration, the evolution of slope from gentle to steep, and the accompanying dynamic response of groundwater spur migration.
