摘　　要：本文主要介绍国外应用落锤式弯沉仪(FWD)进行路面结构评价与罩面设计的基本原理与步骤,对其中反算路面各结构层现场弹性模量的方法,土基模量的非线性数学表达式、路面剩余寿命预估及Miner原理在罩面设计中的应用作了说明。并列举了应用FWD测量路表弯沉盆的优点及FWD在道路设计与评价中的一些基本用途。In this paper,the principles and procedures of structural evaluation of pavements and overlay design are presented, the method of back-analysis of the insitu elastic stiffnesses of each pavement layer,the non-linear elastic model of the subgrade,the assessment of the remaining life of the existing pavement and the application of Miner's rule are also discussed.In addition, the advantage of FWD deflection bowel and FWD application in pavement design and evaluation are illustrated by examples.
