| 摘 要： | 通过化学成分、X-射线衍射以及红外吸收光谱分析,研究了原状炭质泥岩及其生成的炭质泥岩滑带土在物质成分上的变化过程,揭示了两者在干燥和浸润条件下力学性能存在巨大差异的根本原因;通过对炭质泥岩滑带土重塑样的分组快剪试验结果分析,探讨了含水量、干密度等物理指标与抗剪强度参数之间的相关规律性,最终建立了具有实用参考价值的经验性公式。

| Abstract: | The variation procedure of material components from the original carbon mudstone to the slip band of the landslide in coal measure strata is studied by analysis of chemical constitution,X-ray diffraction and infra-red spectrum absorption,and then the ultimate cause for the distinct difference in mechanical properties under the condition of dry and soakage between the two kinds of related materials is given.Finally,on the basis of the results of grouped quick shear tests on the remolding slip band soil samples,this paper discusses the correlation between moisture content,dry density and the shear strength parameters,and gives the empirical formulas with practical value. |
