The invention provides a simulation test device for analyzing the vibration instability of a tailings pond, comprising a motor, a motor fixing bracket, a transmission connecting rod, a connecting rod fixing bracket, a model box and a drum line; the motor is fixed in the motor fixing bracket, and the transmission The connecting rod is set on the connecting rod fixing bracket, one end of the transmission connecting rod is connected with the rotating shaft of the motor, and the other end is connected with the model box, and the model box is placed on the roller line; the transmission connecting rod is used to convert the circular motion of the motor into linear motion, To push the model box to move horizontally on the roller line; the inner bottom of the model box is piled with a permeable dam, and the front and rear side walls of the model box are opened with a plurality of simulation holes symmetrically distributed on the front and rear side walls of the model box. The invention provides horizontal thrust for the model box through the motor and the transmission link to replace the vibration table, thereby overcoming the shortcomings of the traditional vibration test device which are bulky, difficult to move and cumbersome to operate.
Description
technical field [0001] The invention relates to the field of risk simulation analysis of mining engineering, in particular to a simulation test device for vibration instability analysis of a tailings pond. Background technique [0002] Tailings ponds are a major hazard source for metal and nonmetal mines. Tailings ponds are a man-made debris flow hazard with high potential energy. Once landslides, dam failures and other accidents occur, the consequences will be disastrous. Especially under dynamic effects such as earthquakes, since a considerable part of the initial permeable dam, tailing clay, tailing silt, and tailing silt are composed of loose particles, they cannot bear the tension during the vibration process, and large displacements will occur, and even the A landslide occurred on the slope of the tailings pond. [0003] At present, in order to analyze the factors affecting the stability of tailings dams, the simulation test device is generally used to analyze the in...
