FWD与BB工作性能对比试验研究

Comparative Study of Working Performance between FWD and Benkelman Beam

针对目前道路检测领域落锤式弯沉仪(FWD)与贝克曼梁(BB)共存的现状,对两种设备的工作性能如测试稳定性及对行车荷载的模拟能力进行了对比分析.研究结果表明:相对贝克曼梁,落锤式弯沉仪稳定性高,且能较好的模拟行车荷载.

Aiming at the status of co-existence of Falling Weight Deflection（FWD） and the Benkelman Beam（BB） in road detection,the work performances of the two kinds of test equipment such as stability and performance on simulation of vehicle load capacities were compared.The results show that FWD works more stably than BB and it can better simulate the vehicle load.
