The strength characteristics of collapsible Loess during moistening process
Zheng Jiangao Zhang Sumin
The strength of collapsible loess will be decreasing clearly during moistening process, Such characteristic can be well described by a critical surface of strength which is discussed in this paper based on the data obtained from a series of triaxial shear rests. For a given stress level, the moisture content w_(er) is a critical limit of ultimate eguilibrium state. Collapsible loess will lose its bearing capacity at the given stress level, when its moisture content is equal or greater than w_(er).
