多年冻土公路工程分类研究进展与思考

The Advance and Review on Highway Engineering Classification of Permafrost

冻土的工程分类是冻土学研究中一个重点问题,文章在总结和分析国内外多年冻土分类研究的基础上并结合中国现行规范对多年冻土公路工程分类的方法,指出了现行规范所存在的问题,并且提出以影响多年冻土工程性质的综合因素为指标对多年冻土进行工程分类,对我国多年冻土地区工程的建设,尤其对青藏公路的建设具有积极的指导意义。

Engineering classification of permafrost is a big problem needs to make clear in cryopedology.The paper analyzed the actuality of permafrost classification specifications in China and abroad,pointed out the existed problems in the specifications currently used in highway engineering in China.Based on this,puts forward the index of composite factors which atlect the engineering properties of permafrost should be considered in the classification.It is useful to engineering construction in permafrost areas of China,especially to Qinghai-Tibet highway.
