Оценка пучинистости крупно-обломочных грунтов с суглинистым заполнителем (Забайкальский край)

Abstract

Coarse soils are reliable foundations. However, in the presence of sand-clay aggregate cryogenic processes develop in them, which has a negative impact on engineering structures functioning. The research aims in assessing the heaving hazard of coarse soils with different percentages of the sand-clay aggregate. Such soils were field-tested in Zabaikalsky Krai. As a result, the optimum conditions of cryogenic frost heave were determined for them and a statistical model was compiled to assess their heaving hazard.
