运用有限元分析软件ANSYS对机场水泥混凝土双层道面在不同层间接触情况下加铺层的受力及变形规律进行了分析,并根据加铺层板底弯沉盆形状系数计算出层间结合系数。研究结果表明:结合系数能很好地反映双层道面之间的层间结合程度,当层间结合程度不良时会导致加铺层弯沉值及板底应力变大,且距飞机轮载越近,其影响程度越大。因此,在进行机场道面加铺层设计、施工时必须考虑层间接触对加铺层性能的影响。
The finite element analysis software ANSYS is used to analyze the stress and deformation of the overlay layer of airport cement concrete double slab pavement with different layers in contact. According to the shape coefficient of the sinking bowl bottom of the overlay layer, Binding coefficient. The results show that the bonding coefficient can well reflect the degree of interlayer bonding between two pavements. When the bonding between two pavements is not good, the deflection of the overlay and the stress on the bottom of the pavement become larger, The closer it is, the greater its impact. Therefore, the airport pavement overlay design, construction must consider the impact of layer contact on the overlay performance.
