分析了察尔汗盐湖岩盐形成的地理环境及成岩特征;基于CT检测技术,对取自3个不同地方的岩盐原样进行了细(此处大多数用微观)观结构扫描分析,并定性分析了其孔隙特征;通过压汞法试验,定量研究了上述3组岩盐原样和16组分别由不同粒径、不同含水量和不同干密度制成的岩盐样品的孔隙特征,掌握了岩盐的孔隙基本特征及相关参数对岩盐孔隙特征的影响规律。论文的研究成果可以为制定盐湖地区岩盐路基填料的选料标准提供参考。
Based on the CT detection technique, rock salt samples taken from three different places were analyzed in detail (most of them are microscopic) and structural analysis was carried out, and qualitative analysis was made The pore characteristics of rock salt samples made from the above three groups of rock salt samples and 16 sets of rock samples with different particle sizes, different water contents and different dry densities were quantitatively studied by the mercury intrusion test, and the basic characteristics of rock pores And related parameters on rock pore characteristics. The research results of the paper can provide a reference for formulating the material selection criteria of rock salt roadbed packing in Salt Lake area.
