落锤式与贝克曼梁式弯沉仪的对比试验

A Comparative Test of Falling Weight & Benkelman Beam Deflectometers

针对昆山地区市政道路结构,以结构相同的5条沥青路面及20条水泥稳定碎石基层的实测数据为基础,对落锤式弯沉仪(FWD)和贝克曼梁式弯沉仪(BB)在2种不同性质荷载作用下的实测弯沉进行了系统性的对比分析。结论得出,实测弯沉LFWD与LBB有一定的差异,但两者存在良好的相关关系。

Aiming at Kunshan municipal road structure,based on the measured data of 5 asphalt pavements of the same structure and 20 cement stabilized macadam base,the falling weight deflectometer(FWD) and Benkelman Beam deflectometer(BB) have been made a systematic comparative analysis on their measured deflection in two kinds of different loads.The conclusions may draw that the measured deflections of LFWD and LBB have some differences,but there is a good correlation between the two.
