摘要
通过对当前国内外各种常用路面弯沉现场测试设备的工作原理、技术特点及其适用条件的介绍,综合分析各自的优缺点,提出了弯沉自动化检测的重要意义及激光自动弯沉仪在实际检测工作中的重要作用,并结合在贵州扎南公路的使用情况总结了激光自动弯沉仪的现场测试经验及数据修正与评定方法,为准确评定路面弯沉提供了可靠的手段与方法。
The significant meaning of automated measurement of deflection and the importance of laser automatic deflectometer in actual test are presented after introducing the working principle, technical characteristics and suitable conditions of devices which are commonly used for in-situ deflection test all over the world and comparing the advantages and disadvantages separately. The experience of in-situ test and approaches for data correction and judgement for laser automatic deflectometer are summarized by combining the practical use on Zhanan highway of Guizhou, which provides reliable method for deflection judgement.
