| Abstract: | 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 °C. 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. |
