库岸滑坡黏性土与河水物理化学作用试验研究

水库水位周期性升降加剧了河水与库岸滑坡堆积物松散土体之间的水土作用，对库岸表层岩土的工程性质会产生显著影响。从水土作用的角度研究河水对库岸黏性土工程性质的影响，通过X射线衍射试验、Zeta电位试验、可交换阳离子试验、固结快剪试验、电镜扫描试验等，对滑坡黏性土与河水作用前后的组分、微结构和抗剪强度进行了对比试验。结果表明...

Physical and Chemical Reaction Between River Water and Clayey Soil from Reservoir Landslide

Water level fluctuation in reservoir intensifies the water-soil interaction between river water and loose soil of landslide deposit,and thereby profoundly affecting the engineering properties of surface rock-soil.The impact of river water on the engineering property of clayey soil at the reservoir bank is studied from the perspective of water-soil interaction.Contrast tests including X-ray diffraction,Zeta electric potential,exchangeable cation types,shear test for consolidated samples,and SEM are performed...
