对寒冷地区工程基础的冻害起因、特点与防治措施进行了论述。对冻胀力与建筑物荷重静力不平衡与冻害的关系,地基土的颗粒粗细、含水量与冻害及冻害程度的主要原因,多年冻土退化,土的工程性质改变与建筑物基础破坏的因素,地基土发生冻胀对建筑物基础作用力的分布及特征等进行了剖析,并提出防治措施。 The causes, characteristics and prevention and cure measures of frost damage in the foundation of cold area are discussed. The relationship between frost heaving force and the static unbalance of building load and frostbite, the main reason of particle size, water content, frost damage and frost damage of permafrost, the degradation of permafrost, the change of engineering property of soil and the destruction of building foundation Factors, the occurrence of frost heave on the foundation soil, the distribution and characteristics of the foundation force of the building were analyzed, and the prevention measures were put forward.
