摘　　要：从红粘土的形成环境出发 ,通过对红粘土矿物组成、化学成分以及粘土矿物的化学活动性与粘土力学性质的相关联系分析 ,指出红粘土的化学活动性与其粘土矿物的吸附性、离子交换容量、地下水化学成分密切相关 ,并从粘土矿物多种特征出发探讨红粘土的化学活动性与工程环境的相关性。It is pointed out that red clay chemical activity is closely related with its clay mineral adsorption, ion exchange capacity and chemical compositions of underground water by correlation analysis of mineral compositions,chemical compositions of red clay and chemical activity of clay minerals with mechanics character of clay, from the view of red clay forming environment,and the correlation between red clay chemical activity and engineering environment is also discussed on the basis of various characteristics of clay mineral.
