| 英文摘要 | In order to prevent disaster due to progressive failure of highway induced by long-term repeated traffic loads, a dynamic design method for highway sub-grade is proposed in this paper. Based on the field test data of pavement roughness, the influencing factors on vehicle loads are analyzed considering moving velocity and vibration frequency of the traffic loads. A simplified three-layer structure of highway is obtained by adopting the method of Ode mark equivalent hypothesis of modulus-thickness. The computation expression of dynamic deformation of sub-grade is deduced with elasto dynamics theorem and Fourier transform method. Combining the expression of dynamic deformation and the pavement deflection control standard of current specification, the control value of dynamic deformation of sub-grade top and the determination method is derived in the context of compatibility of deformation between pavement and sub-grade. According to the control standard, a new design method of sub-grade on control deformation is advanced and three typical asphalt pavement structures are designed for illustration using this method. |
