摘　　要：首先阐述国内桥梁结构孔道注浆质量的重要性,引入弹性波技术,定性检测桥梁孔道注浆饱满程度。结合工程实例,测试了西北某高速连续刚构桥梁孔道注浆饱满程度,并对所测试桥梁结构孔道注浆异常区域,进行开孔验证。通过验证,表明弹性波技术检测桥梁孔道注浆的准确性,值得大力推广和运用。The importance of grouting quaIity of the bridge structure duct is elaborated first- ly in this paper. Then the elastic wave technique is introduced to test the duct grouting qualitatively. Based on practical examples, the quality of the bridge duct grouting in one northwestern highway is tested and the abnormal areas of the tested is verified by opening pore. The result shows that this technique is worth popularizing.
