Abstract: Due to the complex geological structure of soil slope, and the numerous bank collapse modes, the parameters of bank collapse prediction are difficult to obtain accurately. On the basis of field parameters of bank collapse survey and statistics of 10 large reservoirs, we analysed the influence factors of bank collapse parameters, including geological factors like the types, origin, era, structure and composition of the soil, as well as the softening effect of reservoir water, water dynamic effect caused by reservoir water lifting, and the wind (wave) scouring effect. Also we proposed several methods to calculate the parameters of the prediction of bank collapse. These methods include the field survey method, the engineering analogy method, and the underwater stable slope angle analysis based on particle composition analysis of fractal theory. Hence we established the system of parameters selection through field geological naming and laboratory soil test naming combined with the geological formation.
