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 paper analyzes the current development of deflection detection technology at home and abroad, as well as the problems and shortcomings in the practical application of deflection detection. The overall framework of laser dynamic deflection measurement system and the data acquisition process are introduced. In the later data processing, The Euler-Bernoulli equation was used to calculate the deflection of pavement. The system changed the traditional deflection detection method essentially.
