摘要:
为了计算具有接缝的混凝土路面的应力,提出了一个简化有限元法的计算机程序。该方法适用于文克尔地基上的由五块板组成的路面体系,而荷载只施加在中心板上。中心板与四块边板之间的联系可以由剪力传递效率,或者由传力杆的尺寸和间距来表示。该法与其他方法不同之处在于有限元分析时,只需要考虑一块中心板。为了阐明如何使用该方法以分析机场道面,采用了波音-747飞机为实例,分析的结果表明,假如接缝的传递效率很高,则最不利荷栽位置在中心板的中部,在相反情况下,临近接缝的荷载比中心荷载更不利。
Abstract:
A simplified finite element method programmed for a computer is presented for determining the stresses in jointed concrete pavements. The method is applicable to a five-slab pavement system on a Winkler foundation with the load applied on the central slab. The joints between the central slab and the four side slabs can be specified either by an efficiency of shear transfer or by the size and spacing of dowel bars. The method is different from others in that only the central slab need be considered in the finite element analysis. An example of a Boeing 747 aircraft is given to illustrate the application of the method to the analysis of an airport pavement. The results of the analysis show that the most critical loading position is at the interior of the central slab if the joints are highly efficient; otherwise the loading near to the joints is more critical than that at interior.
