| The development of frozen ground engineering practice put forward some new problems to frozen ground engineering. Frozen ground geotechnical centrifuge modeling technique is an exclusive physical simulation technology for frozen ground engineering, which can realize the coupling of temperature and in-situ stress field, basing on a geotechnical centrifuge. This technique can be used to simulate prototypes in a short time according to the scale factors. In the last thirty years,frozen ground geotechnical centrifuge modeling technique has made rapid development around the world with innovation of heat exchange devices, the consummation of scaling laws and the improvement of testing methods. This technique can provides a new way for the research of frozen ground engineering. The development process of the test devices are reviewed, and the main research and achievements of the research are summarized in this paper. and then, the development trend for frozen ground geotechnical centrifuge modeling technique is predicted. |
