摘要
针对基于落锤式弯沉仪的路面结构层模量线弹性反演在某些情况下的不足之处 ,引入路面材料的非线性模型 ,并结合非线性最小二乘优化 ,研究路面结构层材料非线性特性有限元反演方法 ,通过实测弯沉盆的反演验证 ,表明可以较好地解决在基层或底基层上进行FWD检测 。
In order to overcome the shortcoming in some cases of linear elastic moduli backcalculation theory for flexible pavement based onalling Weight Deflectometer (FWD), a finite element method has been researched, in which material nonlinear model and nonlinear least squares optimization method are integrated It is demonstrated that this method can deal with the backcalculation of moduli based on the data measured on base layer or subbase layer for weak layer identification or construction monitor
