A model test system with a dynamic load device for geotechnical engineering in cold regions is presented.This system consists of a model test tank,a refrigeration device and temperature controller,a dynamic load device,together with sensors and data loggers for detecting stress,deformation,and temperature changes.The system can accommodate soil blocks up to 3 m in length,2.5 m in width,and 1 m in height.The lowest temperature provided by the refrigeration device is-20 ℃.The maximum load provided by the dynamic load device is 100 kN and the vibration frequency of the dynamic load can range from 0.1 to 10 Hz.A number of waveforms,such as sine waves,rectangular waves,triangle waves,and other user-defined waves can be generated by the dynamic load device controller.
