摘要
堆石坝碾压施工中，压实干密度是一项重要的施工质量指标．传统的挖坑取样测试干密度的方法存在费时、费力、采样率很低，数据代表性差等缺点．用表面波无损试验法检测堆石坝碾压压实干密度是一种测试精度高、简捷、快速的新方法．本文就表面波无损试验法的原理，BZJ－3A型表面波压实密度仪的组成、技术指标、操作功能及在筑坝工程中的应用实例等方面作了进一步介绍．
Dry density is an 1mportant parameter 1n c0nstruction quality of the rockfill dam. Dig sampling method for detecting dry dens1ty is conventional method, but this method is not perfect because of long detectlng peri0d, low sample rate, low representive data. The surface wave nondestructive testing is a new meth0d that it has h1gh accuracy, shortcut, high speed for detecting dry density in rockfill dam. This paper introduces principle of the surface wave nondestructive testing, compose of BZJ - 3A surface wave compaction density detector and it's specifications, 0peration function and examples of it's application in constructing dam.
