鄂北膨胀土的矿物组成和化学成分分析

Analysis of mineral composition and chemical components of expansive soil in North Hubei

首先利用X射线衍射(XRD)对鄂北膨胀土中的不同矿物组成进行了鉴定,并根据衍射峰的强度和半高宽定量分析了各成分的含量,然后利用X射线能谱(EDX)对膨胀土中的化学元素组成进行了测定和分析,最后对膨胀土的结核现象进行了分析。其研究成果对评价膨胀土的潮解特性,揭示了膨胀土和改性膨胀土特性以及强度形成机理具有重要的意义,并为今后膨胀土的研究和应用提供了一定的理论依据。

Firstly, through XRD method, the mineral composition and the contents of different compositions of expansive soil in North Hubei are analyzed by diffraction strength and half depth-width quantitatively. Then through EDX method, the chemical components of expansive soil in North Hubei are measured and analyzed. Finally, the phenomenon of subcutaneous nodes is expounded. The research results have great significance to evaluate the deliquescent character of cleaving stone in expansive soil and disclose the cha...
