description The invention discloses a hydro-thermo-mechanical coupled subgrade dynamic response testing device and a method thereof. The device comprises a subgrade body, a water supply system, a loading system,a temperature control system and a data acquisition and processing system. The method comprises the following steps: connection of a data acquisition unit; consolidation and stabilization of the subgrade body; the vacuum insulation process; setting of water supply conditions and operating temperature of a bottom thermostat; the freezing process of the subgrade body; the melting process of the subgrade body; and hydro-thermo-mechanical coupled subgrade dynamic response testing and data acquisition and processing. According to the testing device and the method provided by the invention, by the utilization of a loading frame, a pressure chamber, a constant temperature system, the water supply system and the data processing system and by combining the dynamic loading technology with differentaxial frequencies, the lar
