摘要
采用轴对称有限元模型,对落锤弯沉仪(FW D)荷载下的多层弹性路面体系进行了动力响应分析,并编制了相应的Fortran90程序。将结果和AN SY S计算结果对比,表明模型选用合理,计算结果准确。
Dynamic response of multi-layered pavements subjected to FWD dynamic loads is analyzed by using two-dimensional axisymmetric finite element method. Correspondingly a Fortran90 program is developed. The results are compared with the available classic results to validate the accuracy of the algorithm. The program can be utilized as forward algorithm in back calculation of dynamic parameters, which is significant and valuable in practice.
