基于应力波反射法的桥梁竖向预应力筋管道注浆效果检测

Pipeline Grouting Effect Detection of Bridge Vertical Prestressed Rib Based on Stress-wave Reflection Method

文章结合某连续刚构桥,通过分析应力波反射法的检测原理,试将该检测方法用于桥梁竖向预应力筋波纹管注浆效果的评价,结果表明采用该方法检测桥梁单根预应力筋管道注浆密实度是一种高效、便捷、经济的检测方法。

Combined with a continuous rigid frame bridge,through analyzing the detection principle of stress-wave reflection method,the article tried to use this detection method in assessing the bellow grouting effect of bridge vertical prestressed ribs,the results showed that using this method to detect the grouting compactness of single bridge prestressed rib is an efficient,convenient and economical detection method.
