| 摘 要： | 荷载影响深度是研究机场道面沉降的重要参数。本文采用ABAQUS有限元软件为平台,针对4C、4D和4E等级机场分别提出了相应的＂道面结构-飞机荷载＂组合形式,并借鉴公路研究思路,通过对比基础内的荷载应力与自重应力,分别采用σZ/σB=0.1和σZ/σB=0.2两种判断标准,得到了不同土质、不同等级机场条件下的基础影响深度。研究表明,不同土质对基础影响深度的影响非常小;不同等级机场的基础影响深度相差可达100%。

| Abstract: | Influence depth induced by aircraft load is an important parameter for research airport’s pavement settlement.In this paper,through the establishment of ABAQUS 3D-FEM model,putting forward corresponding ＂pavement structure-aircraft load＂for 4C,4D and 4E grade airport,drawing on the highway research ideas,and comparison with the load stress and gravity stress,using two kinds of judgment criteria that is σZ/ σB = 0.1 and σZ/ σB = 0.2,researches different grade airport’s influence depth with different soil.Studies shows that the influence of different soil to influence depth is very small;difference between different grade airport’s influence depth is up to 100%. |
