Abstract: Based on the hypothesis of elastic layered theory, by analyzing the character of surface deflection basins the algorithms and nomographs for deflection-basin interpretation were developed.
Key words: flexible Pavement, falling veight deflectometer, deflection basin, stiffness evaluation
摘要: 本文以弹性层状体系理论为基础,应用所编制的计算机分析程序,通过大量的计算分析,研究了路表弯沉盆特性与路面结构刚度组成之间的对应关系;在此基础上运用分析比较法,重点以三层体系为研究对象,得出了由路表弯沉、弯沉盆参数来推求路面结构各层弹性模量的计算公式及图表,从而建立了通过落锤式弯沉仪(FWD),在不破损路面的情况下,量测路表弯沉盆,现场快速评定路面结构刚度组成的方法。
关键词: 柔性路面, 落锤式弯沉仪, 弯沉盆, 刚度评定
