摘要
在总结分析国内外已有冻土分类方案的基础上 ,针对中国现行公路工程冻土分类标准中存在的不足之处 ,结合目前对青藏公路沿线多年冻土研究的最新成果 ,提出了以多年冻土含冰特征与多年冻土年平均地温的综合指标——冻土热稳定性为基础的公路工程冻土类型划分方案 ,并对所划分出的三种冻土类型给出了相应的冻土路基设计原则。
Based on the summary and analysis of frozen soil classifications already existing in China and abroad,aimed at the defect of classification standard currently used in highway engineering in China,and combined with the achievement of recent study on the permafrost along Qinghai-Tibet Highway,this paper proposes a new plan of frozen soil classification on the basis of ice content and annual mean temperature of permafrost,i.e.the thermal stability of permafrost. The principles of roadbed design on permafrost are given to the three types of permafrost classified in this paper.
