Abstract

The invention discloses a device for testing the stability of a side slope under the action of earthquakes and rainfall. The key point of the technical scheme is that the device comprises a test box; a transmission section; the earthquake simulation mechanism is arranged at the bottom of the transmission section; the artificial rainfall mechanism is arranged above the simulation side slope model; the earthquake simulation mechanism comprises a vibration bag, and the vibration bag is filled with liquid. The binding box is bound on the periphery and the bottom of the vibration bag; the low-plasticity plate is fixedly connected to the top of the binding box, the low-plasticity plate and the top of the vibration bag are bonded together, and the low-plasticity plate makes contact with the bottom of the transfer section; and a seismic generator; through the arrangement of the vibration bag, simulated seismic waves can be conveniently transmitted to the earth crust from the earth mantle and then transmitted to the simulated slope model through the transmission section, so that the simulated earthquake is closer to the earthquake condition in reality, and through the arrangement of the plurality of earthquake generators, the seismic waves in different directions can be conveniently simulated.
