摘要
钙质砂微观结构和变形机理与陆源砂不同，需采用适用于其特征的试验技术。对钙质砂的土粒比重、孔隙比的测量方法、三轴剪切制样技术、颗粒破碎的评价及强度取值方法进行了探讨。
The microstructure and mechanism of deformation of calcareous sand are different from that of terrogenious sand. It is necessary to use new experiment technique to fit its characters. The methods are disscussed for measuring grain specific gravity and void ratio, preparing sample for triaxial test, evaluating particle crushing and estimating soil strength.
