摘要： 结合沿海某小岛软土地基上的堤防工程，基于强度折减弹塑性有限元数值分析方法，针对不同水位条件下的堤防进行了有限元分析，分别采用简化Bishop法、通用Janbu法和修正Janbu法计算了堤防的安全系数，结果发现，在相同条件下，利用通用Janbu法计算得到的堤防安全系数略小于用简化Bishop法和修正Janbu法得到的结果，研究可为滨海地区堤防工程的稳定性控制提供参考。

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.
