为了分析机场水泥混凝土道面加铺层各计算参数的取值对加铺层厚度的影响,采用《军用机场水泥混凝土道面设计规范》(GJB 1278A-2009)的方法对机场水泥混凝土加铺层厚度进行计算分析。研究结果表明:新、旧水泥混凝土道面间的结合系数对加铺层厚度有明显的影响,特别是结合系数从0增大到0.2时,加铺层厚度减少17.98%~47.54%;加铺层厚度随着加铺层道面板尺寸的增大而增大;增加加铺层混凝土强度可以明显减少隔离式双层道面加铺层的厚度,而增加旧道面混凝土强度可以明显减少结合式双层道面加铺层的厚度;在进行机场水泥混凝土道面加铺层设计、施工时,需要综合考虑各结构参数对加铺层厚度的影响。
In order to analyze the influence of the calculation parameters of airport cement concrete overlay on the thickness of overlay, the method of “Design Code of Military Airport Cement Concrete Pavement” (GJB 1278A-2009) Thickness calculation and analysis. The results show that the bonding coefficient of new and old cement concrete pavement has a significant effect on the thickness of overlay, especially when the bonding coefficient increases from 0 to 0.2, the overlay thickness decreases by 17.98% -47.54% The layer thickness increases with the increase of the size of the overlay pavement slab; increasing the strength of the overlay concrete can obviously reduce the thickness of the isolated double pavements, while increasing the strength of the concrete of the old pavements can significantly reduce the combined double Layer pavement overlay thickness; airport cement concrete pavement overlay design, construction, the need to consider the various structural parameters on the overlay thickness.
