The toe-shooting method has been widely used to build nearshore groynes in China. The proper method for analyzing the slope stability of this kind of groyne is however not found at present. Based on the limit equilibrium method a typical groyne located in a deep silt and soft soil mass aside is first analyzed. A new method calculating the factor of safety is then proposed for the slope stability of these groynes. Finally
the method presented and other four common methods are used to analyze the slope stability of a practical groyne. It is shown that the proposed method for slope stability of this groyne can give the more realistic factor of safety than the other four common methods.
