预应力管道灌浆质量检测方法的现状和进展

Comparison of Test Methods for Bolt & Anchor Filling Percentage

文章通过分类比较的方法,介绍了目前国内外最常用的测试预应力管道灌浆质量的钻芯取样法、电磁波雷达法、X光、γ射线法、弹性波冲击回波法、超声波透射法以及透过等几种测试方法,认为基于冲击弹性波的一系列技术是可行和有发展前途的方法。

The filling quality is very important for the pre-stressed structures.Compared the methods by category,introduced the most commonly used methods for grouting quality test,such as drill core sampling,electromagnetic wave radar,X-ray,γ-ray method,elastic wave,impact echo method,ultrasonic transmission method etc.,are introduced in this paper,.It is proved that the series of technology methods based on impact elastic waves are feasible and promising.
