摘　　要：目前利用落锤式弯沉仪测得的时程曲线进行路面结构层材料特性反算方法发展迅速。通过分析现有路面模量反演方法的优缺点,并将比例边界有限元方法引入路面弯沉的求解中,与其有限元的结合,解决了有限元方法由于人工边界的引入而存在的问题,并结合系统识别方法,实现路面模量的反演。The inverse calculation method of pavement layer material characteristics using time curve measured by falling weight deflectometer develops rapidly at present.This paper analyzes the advantages and disadvantages of inversion method for the existing pavement modulus,and introduces scaled boundary finite element method into the solution of pavement deflection,which solves the problem of finite element method for its artificial boundary.Combined with system recognition method,inversion of pavement modulus can be realized.
