LI Hong-sheng, YANG Hai-tian, LIU Zeng-li, et al. Evaluation of anti-frost heave ability via replacement of ground soil based on generalized strength criterion[J]. 2003, 24(5).DOI:
a new method is presented to evaluate the ability of anti–frost-heave ability via the replacement of ground soil. Compared with the conventional methods
the criterion proposed is more reasonable since more factors are taken into account. The frost-heave force is considered as a kind of external load
and the defects of frozen soil are treated as cracks. The toughness of frozen soil
as an important factor
is introduced in the new criterion. A numerical example of a retaining wall is given to analyze the stability and strength before and after replacement.
