The feasibility analysis which selects the spreading cement site of service area of expressway as unsupported random launching site is studied in this paper. The structure stress in cement slab is calculated based on load characteristic of launch vehicle, and the key influence factors of bearing capacity of rigid pavement is discussed. Analysis result shows, to flexural-tensile stress of pavement bottom, the thickness of rigid pavement has significant influence comparing with other factors, and the flexural-tensile stress of pavement bottom will increase with the increment of pavement modular, while decrease with the increment of equivalent modular of top surface of soil base. To verify the accuracy of the built influence regularity of stress change in rigid cement slab, a 3D finite element model of optional site is created, which used to certify the vary regularity achieved by theoretical analysis. Simulation and comparison result shows the influence regularity to load stress of the thickness of rigid pavement, and pavement modular generated by theoretical analysis coincides with 3D finite element model.
