Based on the equivalence principle of bending deflection and torsional displacement, the concentrated vertical load which acts on the center of a continuously reinforced concrete pavement (CRCP) is translated into an equivalent half-wave sine load by Fourier transform. On the basis of this transform and deformation harmony condition of crack, the equations of load transfer are established. According to the translation principle of the force, the equations of load transfer of adjacent slabs are worked out. With the small deflection theory of elastic thin slabs, the bending deflection and torsional displacement formulas of CRCP under the concentrated vertical load with hollow foundation are deduced, which is verified by the results of finite element(FE). The results show that the characteristic of CRCP after cracking is related to the rigidity factor which is proportional to the spacing of adjacent cracks and the width of CRCP.
