摘要
根据美国、原苏联和我国冻土分类的现行标准的分析，目前有关冻土分类基本上按两种方法进行。一是根据土的基本物理性质和含冰特征进行分类，二是根据冻土特殊工程特性进行分类。各国对冻土的描述及分类已从定性向定量发展，冻土分类方法正处于从单项规程到综合规范、从部门标准向国家标准和国际标准的方向过渡。建议我国的冻土分类按下列步骤进行：１）采用国标《土的分类标准》ＧＢＪ１４５－９０作为土统一分类标准。２）引进《人工冻土的分类与实验室试验》国际编写小组推荐的冻土描述和分类，与国标ＧＢＪ１４５－９０相配套，组成按土的基本物理性质进行冻土分类系统。３）根据各工程特点，按冻土特殊工程性质进行的分类，组成专门的冻土工程分类系统。
According to the current standards of description and classification of frozen soils in theUnited States,Russia and China there are two ways for classification of frozen soils．The firstis based on the physical properties and ice characteristic of soils and the second is based on itsspecial engineering behaviour．The classifications go in the directions from qualitative aspectto quantitative aspect and from local and state standards to the international．Suggestions forcompiling standard in our country are as follows：a.taking the Chinese standard of grainsize division of soils GBJ 145－90，as unified soil classification system；b．introducing thedescription and classification of frozen soils based on the physical properties and ice charac-teristics of soils，recommended by the international working group．c. raising classificationsystem of frozen soils for engineering purpose according to the special engineering propertiesof frozen soils.
