Short summary
In this paper, artificial model tests were used to observe the changes of soil moisture content and pore water pressure, as well as macroscopic and microscopic phenomena of gravel soil. In addition, the mathematical formula of the critical state was derived from the triaxial test data. Finally, the mechanical states of gravel soil were determined. In the process of landslide initiation, dilatation and contraction were two types of gravel soil state, but dilatation was dominant.
In this paper, artificial model tests were used to observe the changes of soil moisture content...
