Impact load dynamic seepage device and method

The invention discloses an impact load dynamic seepage device and method, the device comprises a loading device, a device main body and a water supply system, the loading device is arranged in the device main body, and the water supply system is connected with the device main body. The invention provides a dynamic seepage device and method under an impact load, aiming at solving the technical requirements that how to solve most sand liquefaction problems at present is completed under the condition of vibration load or large shear displacement, a non-drainage state is mostly kept in the research, and liquefaction response after the bottom of saturated sand is impacted is rarely considered. The sand sample change and the liquefaction response when the sand is impacted at the bottom can be well observed, and the change of the seepage velocity under the dynamic load is analyzed through data recorded by the sensor, so that the sand sample change and the liquefaction response when the sand is impacted at the bottom
