Abstract: The traditional rock and soil frost heave deformation characteristics analysis test is time-consuming and expensive. Therefore, an experimental study method of rock and soil frost heave deformation characteristics based on the pore distribution model is proposed. The pore distribution model was constructed to calculate the stress intensity factor formed by the point force and the distributed gravity, and then the frost heave displacement was obtained, and the frost heave deformation characteristics were analysed. The test results show that the running time of this study is saved by at least 2 min, and the average test cost is 14,951 million Yuan. Through the results of soil strain energy release rate and soil moisture content obtained, the effectiveness of the frost heave deformation characteristic test of rock and soil is fully verified.

Keywords: pore distribution model; frost heave of rock and soil; deformation characteristics; experimental study.
