摘　　要：利用天山北麓水磨河流域细土平原区硫酸(亚硫酸)盐渍土无荷载和有荷载条件下多次冻融盐-冻胀变形试验研究成果,采用单向分层总和法和积分法建立了硫酸(亚硫酸)盐渍土盐-冻胀变形预报模型,并利用原位观测分析验证模型的可靠性,提出了建立地温观测体系和建立盐-冻胀变形试验标准的建议。Based on the experiment conclusion of sulfate(sulfurous) salty soil of multiple freeze-thaw salt-frost heaving deformation on the condition of with and without load in the fine soil plain area of Shuimo river basin in Tian Mountain northern foot,this paper constructs forecast model of salt-frost heaving deformation of sulfate (sulfurous) salty soil by the one-way stratification sum method and integration method,puts forward the suggestion of building the observation system of ground temperature and experiment standard of salt-frost heaving deforma tion by using the dependability of in-situ observation model.
