浅谈灌砂法试验

On the experiment of sand replacement method

为了保证灌砂法密度试验的准确性,从仪器的选择、标定灌砂筒下部锥体内量砂的质量及标定量砂的单位质量等方面介绍了该试验的方法步骤,就灌砂法的原理和适用范围做了概述,提出了试验操作过程应注意的要点,从而提高试验精度。

To assure the accuracy of the density experiment of sand replacement method, from the selection of equipment, the calibration of the mass inside the down cone of sane tube and the calibration of the unit mass of measuring the sand it introduces the methods and progresses of the experiment. And it discusses the principles and application fields of sand replacement method, puts forward the points that should attention in the operation of experiment, so to increase the accuracy of experiment.
