Abstract: In order to study the effect of the depth and spacing of continuous carbon fiber heating wires on the temperature uniformity of the concrete slab,and the influences of XPS insulation layer,the transient heat transfer model of continuous carbon fiber heated airport pavement temperature rise and deicing snow was established by using finite element analysis software Ansys.It mainly simulates the temperature rise and deicing process of the pavement.It is found that when the spacing is less than or equal to 100 mm and the depth is no less than 50 mm, the surface temperature uniformity is capable.Through the quantitative calculation of"effective melting time"and"effective utilization of energy",it is proved that the layout of XPS heat insulation layer has a good insulation effect and it provides a theoretical basis for its application in airport pavement deicing.
