【 摘 要 】

Frost heaving characteristics of canal foundation soil in HaDashan area are analyzed and studied by indoor frost heave test and field test. The research results show that, under the experimental conditions, the frost heave of the canal soil increases with time and temperature, but after a certain period of time, the amount of frost heave tends to be stable; the frost heaving process is divided into 4 stages: unstable freezing, continuous freezing, stable freezing and thawing. The research results have certain guiding significance for the construction of large channel in HaDashan area.
