我国分布有大面积的多年冻土,根据我国机场建设的中长期规划,未来将在多年冻土区修建大量机场,这些机场的修建将不能避免多年冻土问题.国内关于冻土区机场跑道修筑的经验非常有限,国外则开始的较早,并积累了一些经验.总结分析国内外多年冻土区机场跑道修筑技术的现状,其跑道类型主要有:基岩跑道、开挖换填法修筑的跑道、铺设隔热层的跑道、安装热管的跑道,共4类.由于我国多年冻土区的特殊性,国外的跑道修筑经验只能在一定程度上参考.由于飞机跑道不同于铁(公)路的特殊性,近年国内在冻土区铁(公)路的修建过程中采用的稳定冻土地基的工程措施如何应用到机场跑道的建设上,仍需进一步研究、验证和实践.将来在我国多年冻土区修建机场跑道,应结合国外已有的技术和经验,并以我国在多年冻土区线性工程中已取得的经验作为基础,进一步研究我国多年冻土区机场跑道修筑的关键技术.
According to the long-term planning of airport construction in our country, a large number of airports will be constructed in the permafrost region in the future, and the construction of these airports will not be able to avoid the problem of permafrost. China’s construction of airport runways in permafrost regions Of the experience is very limited, and foreign countries started earlier and accumulated some experiences.A summary and analysis of the status quo of airport runway construction technology in permafrost regions at home and abroad are as follows: runway of bedrock, excavation and replacement Runway, insulation runway, heat pipe runway installation, a total of 4. Due to the peculiarities of the permafrost region in China, foreign runway construction experience can only be used to a certain extent.As the runway is different from the iron (public) The particularity of the road, how to apply the engineering measures of stabilizing frozen ground in the process of building the iron (public) road in the permafrost regions to the construction of airport runways in China still need further research, verification and practice in the future. The construction of airport runways in permafrost regions should be further studied based on the experience and experience already gained in the linear engineering of the permafrost region based on the existing technologies and experiences abroad The key technology country permafrost zone of the airport runway construction.
