摘要: 多年冻土的年平均温度和含冰类型作为表征多年冻土特征的两个基本指标,在一定程度上决定了多年冻土区公路工程所要采取的技术措施. 因此,年平均温度和含冰类型是多年冻土公路工程设计和施工中必须考虑的两个因素. 通过对青康公路国道214线沿线冻土工程地质状况调查和公路病害的分析,结合区域内气象水文等资料,研究了公路工程病害对多年冻土年平均温度和含冰类型的敏感性,查清了影响公路病害的主要因素. 研究结果为不同地温分区、不同含冰量多年冻土区公路病害防治技术措施的选择提供了科学依据,将减少或延缓多年冻土区公路病害的发生,提高工程质量,节省养护成本,保障安全运营,促进冻土区经济社会的发展.

Abstract: The annual mean ground temperature and ice content, the two basic indexes of permafrost, determine the technical measures which are applied to deal with highway diseases. Based on a comprehensive investigation of engineering geological condition, hydrographical and meteorological conditions and highway diseases of National Highway 214, the sensitivity of ground temperatures and ice contents were studied, and then the main influencing factors of highway diseases were identified. The study results will be useful for choosing suitable technical measures for different permafrost regions with different temperatures or ice contents. Also they will help to reduce the occurrence of highway disease and the cost of highway maintenance, and to delay the occurrence of highway disease and to ensure the safety of highway operation. The improvement of traffic condition will accelerate the development of economy and society in permafrost regions.

Key words: permafrost, highway disease, ground temperature, ice content type, sensitivity analysis
