摘　　要：根据国道214线多年冻土工程地质勘察资料,对沿线多年冻土的工程地质特性进行了对比分析;总结了沿线多年冻土的分布情况,得出了在外界气温升高及人类工程活动的影响下,沿线的多年冻土都呈现退化趋势,并分析了其退化特征和退化原因;利用数值模拟仿真手段,对沿线多年冻土的退化趋势进行预测分析。Based on the prospecting information about permafrost along National Road 214, a comparative analysis was carried out in connection to the engineering geological characteristics of the permafrost, and then generalized its distribution along the road. As a result, the conclusion that the permafrost presents the trend of degeneration under impact of outside temperature increase and human being＇s engineering activities is obtained; simultaneously, the features and causes of degeneration are analyzed. In addition, with numerical simulation method, the trend of degeneration herein is predicted.
