摘要
通过对贵州红粘土大量实验数据的统计和分析,发现贵州红粘土的稠度状态有其自身的特点:一是用含水比划分出在自然状态下贵州红粘土常处于硬塑和可塑状态且有地域性差异;二是用液性指数对贵州红粘土稠度状态进行划分,其结果与用含水比划分结果有较大偏差。结合红粘土特殊成分结构分析,认为其原因是红土化作用的程度不同和土中存在大量结合水。采用代数转换的方法分析得出适合贵州红粘土稠度状态划分的液性指数等效范围,便于与其它土类状态划分范围进行对比,体现贵州红粘土稠度状态划分上的特殊性。
Based on the statistics and analyses of many experimental data of the red clay in Guizhou,it is founnd that the consistency state of the red clay in Guizhou has its own characteristics:(1) water content ratio is used to partition the consistency state of Guizhou red clay in natural state,which is often in hard plastic and plastic states and regional difference exists;(2) a large deviation exists when liquidity index is used to partition the consistency state of the red clay in Guizhou.Combined with the analysis of special composition structure of the red clay,it is believed that the reason for these is the different laterization degree and the soil with a lot bound water.The liquidity index equivalent range appropriate to the state division of the red clay in Guizhou are analyzed by using algebra conversion.The results are easily compared with the classification standard of consistency state of other soil types.This can explain the special traits of the red clay in classification of consistency state.
