摘要
路面的动态特性是目前各国研究的热点,其中动态模量又是这一特性的一个基本参数。文章详细介绍了基于FWD野外动态模量的各种反算方法及其优缺点,并论述了基于静力层状弹性体理论的路面动态模量反析程序所存在的局限性及合理性,最后提出用有限元反析路面模量及在我国开展此项研究的基本原则。
The dynamic performance of pavement is a hot -topic of study throughout world, while the dynamic modulus is a basic parameter. This paper describes the methods of inverse analysis on dynamic modulus of field pavement with falling weight deflectometer （ FWD ） ,and its advantages and disadvantages. It discusses the limitation and rationality on back analysis based on layered elastic theory for dynamic modulus of pavement, and finally indicates that the modulus of pavement is analyzed through finite element method with the basic principles of doing research in China.
