| Abstract: | 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. |
