摘 要：Soil is a heterogeneous medium which consist of liquid,solid and gases *** solid and liquid phases play an essential role in soil spontaneous electrical phenomena and in behaviour of electrical fields,artificially created in soil.A method is worked out to determine the soil friction coefficient and specific adhesion for clayey sand *** specific effective cohesion,specific internal friction angle and specific resistivity of tropical clayey sand soils were determined in this *** order to determine the specific friction coefficient and specific adhesion of clayey sand soils,the soil slipping resistance should be assessed at several different values of pressure between the slipping *** direct shear test,resistivity test,soil’s consistency and atterberg limit tests were carried out in purposed to determine the physical characterizations of clayey sand *** on the basic of this opinion,by the means of least squares method（LSM）,the soil’s friction coefficient and specific adhesion together with specific effective cohesion,specific internal friction angle and their specific resistivity of tropical clayey sand soils is successfully *** research also systematically investigates the physical behaviour and their correlations of clayey sand soils properties during fixed period which potentially for hazard assessment.
