Abstract: This paper presents a case study of analytical results of levees on soft soils in coastal region. Three methods of analysis: Simplified Bishop's method, General Janbu Method and Modified Janbu Method, are studied respectively by using the strength reduction principles. The safety factors are obtained and the results of the three methods are compared. It is concluded that the factor of safety obtained from the General Janbu Method is slightly less than those resulted from both the Simplified Bishop's Method and the Modified Janbu Method.

Key words:  Strength Reduction Method, Levees, Soft Soils, Slope Stability
