摘要
分析了当前国内外路面弯沉检测技术的发展现状,以及弯沉检测在实际应用中存在的问题和不足,介绍了激光动态弯沉测量系统的总体框架,数据采集流程,在后期数据处理上采用欧拉-伯努利方程反演计算得到路面的弯沉值,系统从本质上改变了传统的弯沉检测方法。
This article analyses the current development situa- tion of pavement deflection detection technology in home and abroad. According to these, the article also shows us some prob- lems and deficiency of road deflection testing in real applica- tion. This article introduces the framework of laser dynamic de- flection measurement system and the data collection process. On the other hand, the article uses Euler-Bernoulli Equation to back analysis the collecting data and gets the pavement deflec- tion. This system essentially has changed the traditional detec- tion method of the deflection.
