钙质珊瑚砂工程性质归纳分析

Engineering Parameters of Calcareous Coral Sand

我国南海遍布着钙质珊瑚砂,与传统的石英砂相比,钙质珊瑚砂具有易破碎、高压缩和低强度等特性,因此,工程建设中需要给予特殊关注。为了便于工程应用,对国内外钙质砂的物理力学特性进行了归纳分析,如颗粒成分、颗粒比重、颗粒级配、不均匀系数、最大最小干密度、有效内摩擦角等参数,为后续工程建设提供了参数来源和参考依据。

Calcareous coral sand is distributed in the South China Sea widely. It has characteristics of strong crushability,high compressibility and low strength compared with traditional quartz sand. Thus,it should be paid more attentions. To facilitate the practical engineering,the physical and mechanical performances are summarized,such as the chemistry contents,static gravity,particle diameter,non-uniform coefficient,the maximum and minimum density and effective frictional angle. This study supplies the parameters for reference.
