- Abstract
A three-dimensional finite element model which consists of thirty full-scale slabs is established for analyzing the mechanical responses of cement concrete airport pavement under aircraft dynamic loads and detecting its capacity under aircraft taxiing. And the joint loading-transfer effect between slabs is considered in the model. The mathematical models between displacement peaks in test area and elasticity modulus of each pavement structure layer are built by calculating plenty of vertical displacements which range over different modulus combinations according to actual runway structure. The results show that the peak value of vertical displacement has linear relationship with surface thickness, logarithmic relationship with pavement elastic modulus and exponential relationship with the resilient modulus of foundation. The resilient moduli of base course and bed course influence little on vertical displacements.
