Abstract

Abstract: In this paperby taking the pore water pressure and the hydrostatic confining pressure into consideration three typical calculating models of cohesive riverbank stability were presented via suitable optimization and were then applied to a practical stability measurement．The corresponding results were finally comparedwith the conclusion thatfor natural riverbanksthe predigesting model is simpler and more applicablebut is less precisewhile for the prediction of riverbank shape after failurethe probability model is betterand the precision of the layered model is the highest in the three modelsalthough its calculating load is the greatest．These three models are all applicable to the stability calculation of cohesive riverbanks with a plane-like failure．

Key words: cohesive riverbank, stability, mass failure
