Regional collapse characteristics of intact loess and its rate of potential collapse

In this paper,collapse characteristics of intact loess from three typical loess areas under different moisture condition are studied,and the principles of loess collapsibility influenced by water content,dry density as well as pressure and behaviors of these in different loess are approached respectively.Base on the collapsibility difference existing in different loess area,a concept of rate of potential collapse is presented,and the test results show that it can be used to analyses the loess collapsibility and reflect the structure characteristics for different kinds of loess preferably.
