【Abstract】 Distinguishing accurately reflected wave is key of non damaging inspection to the strength and thickness of concrete highway surface.In this paper,a physical model experiment method of distinguishing accurately reflected wave is presented.Two layers model simulate the surface and bed of highway.With special observation system and multiform differentiation method,drawing exactly the time and velocity of reflected wave is simple.The precision of non damaging inspection to the strength and thickness of concrete highway surface is on the large increase.更多还原
