摘 要:为研究飞机滑跑时机场跑道下伏隧道结构的稳定性,通过建立“五点接触式”飞机六自由度的动力学方程,构建机场跑道-土层-隧道结构协同变形数值计算模型,重点分析机型、道面类型和埋置深度等因素对隧道结构稳定性的影响。结果表明:在不同机型的飞机荷载作用下,主起落架机轮的分布位置越集中,对隧道结构的稳定性影响越大;柔性道面在应力扩散的衰减效应方面明显优于刚性道面,隧道结构的拱顶位置变形程度比其他位置更为显著;随着隧道结构埋置深度的增加,飞机荷载对隧道结构的扰动效应呈现衰减趋势,当隧道埋深结构超过64 m时,隧道结构不再承受飞机荷载的扰动效应。In order to study the stability of the tunnel structure under the airport runway when the aircraft is running,the numerical calculation model of the runway,soil layer and tunnel structure co-deformation was constructed by establishing the six-degree-of-freedom dynamic equation of the“five-point contact”aircraft.The influence of the aircraft type,pavement type and buried depth on the stability of the tunnel structure was analyzed.The results show that the more concentrated the distribution position of the main landing gear wheel is,the greater the influence on the stability of the tunnel structure under different aircraft loads.The attenuation effect of stress diffusion on the flexible tunnel surface is obviously better than that on the rigid tunnel surface,and the deformation degree of the arch top is more significant than other locations.With the increase of the buried depth of the tunnel structure,the disturbance effect of aircraft load on the tunnel structure shows a decreasing trend.When the buried depth of the tunnel structure exceeds 64 m,the tunnel structure no longer bears the disturbance effect of aircraft load.
