The ACN-PCN system of rating airport pavements is designated by the International Civil Aviation Organization (ICAO) as the only approved method for reporting strength. ACN-PCN是ICAO制定的一种计算道面强度的方法,唯一批准用来报告强度的方法。 The ICAO system for civil airport pavements involves comparis...
ACN values for selected aircraft have been calculated by the International Civil Aviation Organization (ICAO) using two computer programs, one forrigid pavements and the other for flexible pavements. 选定飞机的ACN值由ICAO计算,使用两种计算模式,一种是刚性道面,一种是柔性道面。 重心越靠后,ACN值越大,...

该方法的本质是通过计算板边应力倒推最大飞机容许重量,将该重量作为当量单轮荷载的2倍,进而通过ACN插值即可得到PCN。 计算方法如下:初拟评价机型的重量G,采用ABAQUS大型通用有限元软件计算四边自由条件下道面板边荷载应力σe,考虑接缝传荷作用引起的应力折减作用,确定板边计算应力σp,根据混凝土材料弯拉疲劳公式计算...
