| 摘 要： | 路面模量反算,是根据落锤式弯沉仪FWD等公路无损检测仪器测得的弯沉盆数据,利用力学理论和数学方法,通过弯沉盆的拟合来反求路面的材料特性参数。该文利用遗传算法反算路面结构层的模量,计算结果表明稳定性好,结果不受初始值的影响,收敛于全部的最优解,反算值可达到令人满意的精度。

| Abstract: | The inverse analysis of pavement modulus is based on the inflection basin data measured by the highway non-destructive testing instrument of falling weight deflectometer FWD.It is to utilize the mechanics theory and mathematics method and to reverse the material characteristic parameter of pavement through simulating fitting of inflection basin.The article uses the genetic algorithms to inversely calculate the modulus of pavement structure layer.The computational results make clearly that the stability is g... |
