摘　　要：路面结构力学认为路面结构破坏的根本原因与挠度无关[1],而是由于过大的应力应变造成的。落锤式弯沉仪应用后,通过弯沉盆参数来反算路面模量的方法得到实现。因此,基于FWD弯沉盆参数对路面进行快速评价成为道路检测的重点。Pavement damage that the root causes of pavement structure has nothing to do with the deflection [1],but because of excessive stress and strain caused. Falling Weight Deflectometer application,the deflection basin parameters by inverse methods of pavement layer moduli are achieved.Therefore,based on FWD deflection basin parameters for rapid assessment on the road to become the focus of road testing.

关 键 词：应力 弹性模量 弯沉盆参数
