Abstract A threedimensional finite model of concrete pavement was established to suit for the concrete pavement in highway tunnel. A nonlinear regression method was used when considering the effect of structural factors. The calculating formula of the tensile stress on the bottom of the slab and the tensile stress on the slab surface was presented. Based on the admitted fatigue tensile stress as design index, the design mehtod of the concrete pavement in highway tunnel was concluded, and the calculating formula of slab thickness was also put foword. An engineering example was used to validate the method. It provides a theory base for the pavement design of the concrete pavement in highway tunnel.
