| 摘 要： | 落锤式弯沉仪(FWD)作为一种快速测试仪器,如何合理利用其所测数据来评定路面的剩余寿命,从而确定路面的罩面厚度,是道路研究的一个重要课题.文中提出应用FWD所测弯沉数据,通过利用反算模量来进行罩面厚度的设计方法.在力学模型与破坏准则的选取上借鉴路面力学分析中较合理的方法,提出一种基于FWD的力学经验设计方法.

| Abstract: | How to reasonably use the data tested from FWD to predict the remaining life of pavement, even to design the width of the overlay, is an important and difficult research project in road engineering. In this article, an ideal that based on the moduli backcalculated from deflection data of FWD was put forward in overlay thickness design method. A new mechanistic-empirical procedure based on FWD is developed in this paper according to the information from the other country and our own. The choices of mechanistic model and damage model of this method take advantage of the reasonable method in the analysis of mechanics of the pavement. |
