附加质量法在水布垭堆石体密度测定中的应用

介绍了附加质量法测定堆石体密度的基本原理、仪器设备及现场测试过程,并结合水布垭大坝一期填筑工程堆石体密度测定工作,分析了该方法的有效性。测试结果表明,该方法不但具有现场测试快速、轻便、无损和精度高等优点,而且适用于不同粒径组成的堆石体,在堆石体密度测定中具有广阔的应用前景。

Application of method of additive mass to density measurement of rock-fill object in Shuibuya water control project

Following an introduction on the testing principle,instrument and equipment,and field signal acquisition process for method of additive mass, this paper deals briefly with its availability on the density measurement of rock-fill object in the Shubuya Dam One Issue Project. The testing results indicate that this method not only has rapid, portable, non-destructive, and precision high, but also suitable for density measurement of rock-fill object made up of different grains. It is proved that method of additive mass is obviously effective and hence shows fairly good application prospects in the density measurement of rock-fill object.
