【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 temperature and ice type of permafrost are two basic indexes to characterize the characteristics of permafrost, which to some extent determine the technical measures to be adopted in highway engineering in permafrost regions. The annual mean temperature and ice type are two factors that must be considered in the design and construction of permafrost highway engineering. Based on the meteorological and hydrological data in the region, the sensitivity of highway engineering diseases to the annual mean temperature of permafrost and the types of ice in permafrost is studied, and the main factors affecting highway diseases are identified. The selection of technical measures to prevent and cure highway diseases in permafrost regions with different ice content for many years provides a scientific basis, which will reduce or delay the occurrence of highway diseases in permafrost regions, improve engineering quality, save maintenance costs, and ensure safe operation. Promote the economic and social development of frozen earth regions.
