Abstract

为探讨泥石流多发区典型细黏土浆体流变特性,选取云南小江流域和甘肃白龙江流域典型土,通过流变试验、颗粒级配试验和矿物组分分析方法,比较分析小江红土和白龙江马兰黄土的泥石流浆体流变特性及其影响因素。

Other Abstract

The slurry rheological properties of debris flow and its impact factors are major content of debris flow dynamics research.In order to study rhelogical properties of typical fine clay in the prone area of debris flow,the debris flow slurry rheological properties and its impact factors of the red soil of Xiao River and the yellow soil of Malan,Bailong River were studied and compared with rheological experiment,particle size experiment and mineral composition analysis method.It was found that along with the increase of density,shearing stress,yield stress and stiffness index of both red and yellow soil indicated a trend of growth,with more obvious growth range under high density.Besides,under the condition of the same density,the three indicators of red soil were significantly higher than that of the yellow soil.Also the shearing stress of red and yellow soil in index correlated to the volume concentration.For red and yellow slurry rheological properties,the impact of density was most significant.In addition,it was discovered that the grain size distribution,clay granule contents,mineral composition and its content were the important causes for the differences of red and yellow soil rheological properties as well.The results could be used to reveal the mechanism of debris flow hazard in the two areas.
