In this paper，taking the typical bank slope of Jiangxi Province as an example，combining with the topography，development stratum and lithologic character，slope structure and material composition of the reservoir bank，this paper analyzes the engineering geological features and uses the indoor and outdoor test results to study the effect of its resistance shear strength characteristics and permeability characteristics，the material composition and structural characteristics of typical soil bank slope are obtained，which provide scientific basis for the effective monitoring and scientific prediction of bank slope stability and taking reasonable treatment measures.
