Abstract:
Through the finite element method,the efect of various factors ( surface course thickness and mod-ulus,functional course thickness and modulus，base thickness,soil modulus and running speed) of semi-rigidbase cement concrete pavement structure with functional course under the vehicle dynamic load on the mechan-ical response was revealed. By using the grey relation analysis,the influence of various factors was given aquantitative analysis.Besides,the formula of the pavement structure mechanical response ( surface deflectiondifference，tensile stress at the bottom of surface course,shear stress on the top of functional course and ten-sile stress at the bottom of base ) were obtained by the regression analysis, which can provide theoretical direc-tion for the structure design and construction of cement concrete with functional course.
