摘要
季冻土地区机场在季节变化过程中,受冻融循环影响,机场道面易出现裂纹、错台、断裂等形式的冻胀破坏,严重威胁机场飞行保障安全。为此,文中对东北地区2个新建机场道面冻胀行为进行持续观测,得到其冻胀变形规律,在此基础上结合现有理论研究,进一步探讨预防冻胀破坏的具体措施,为季冻土地区机场道面施工提供参考。
In the seasonal change process of airports in the seasonally frozen soil area, affected by the freezing-thawing cycle, the airport pavement is prone to frost heave damage in the form of cracks, platform faults and fractures, which seriously threatens the flight safety of airports. In this paper, the frost heave behavior of two newly built airport pavement in northeast China is continuously observed, and the frost heave deformation law is obtained. On this basis, combined with the existing theoretical research, the specific measures to prevent frost heave damage are further discussed, and provide reference for the construction of airport pavement in seasonally frozen soil area.
