摘　　要：通过冻胀率与切向冻胀力的测定 ,建立了季节性冻土切向冻胀力与土的冻胀性关系最佳曲线模型 ,并依据该模型推荐了不同冻胀土类的胀切向冻胀力值 。On the base of brief discussion on tangential frozen heaving force, frozen property of soil and their relationship,Test and observation data gained in many years(tangential frozen heaving forces and frozen property of soils)were processed mathematically.An optimum curve model between tangential frozen heaving force and frozen property of soil was presented,It is recommend the value of tangential frozen heaving force based on this model be applied practically.

关 键 词：季节冻土 切向冻胀力 冻胀率
