摘要
土基回弹模量是道路工程路面结构设计的主要参数,其测试方法较多,文章针对目前比较常用的土基回弹模量测试方法-贝克曼梁法和FWD法进行了分析。通过试验,得出了两种方法测得的弯沉值之间的相关关系,并对两种方法测得的弯沉值的可靠性进行了研究。
The subgrade rebound modulus with various testing methods, is one of the main param- eters of pavement design. This paper studies the common testing method of subgrade rebound modu- lus--Benkelman beam and FWD. From the experiments, the correlation of deflections by Benkelman beam and FWD is respectively obtained. Furthermore, the reliability of deflections of the two ways is also studied.
