摘　　要：落锤式弯沉仪(FWD)是一种脉冲动力弯沉检测仪器,主要由荷载发生器、弯沉检测器、计算系统等部分构成,通过模拟车辆行驶过程中对路面结构层产生的冲击力,检测出路面的变形数据,从而达到检测路面结构层弯沉值的目的,能反映路面结构的综合承受荷载的能力。由于其检测速度快,对路面不会造成破损,检测精度高的特点,被广泛应用于公路路面弯沉检测中,本文对落锤式弯沉仪在公路路面弯沉检测的应用进行简要探讨。The Falling Weight Deflectometer(FWD)is a pulse dynamic deflection detection instrument,mainly composed of a load generator,deflection detector,calculation system,and other parts.By simulating the impact force generated by the vehicle during driving on the road structure layer,the deformation data of the road surface is detected to achieve the purpose of detecting the deflection value of the road structure layer,which can reflect the comprehensive load-bearing capacity of the road structure.Due to its fast detection speed,no damage to the road surface,and high detection accuracy,it is widely used in highway pavement deflection detection.This article briefly discusses the application of the drop hammer deflection instrument in highway pavement deflection detection.
