摘　　要：海堤作为围海工程的主体,准确计算和控制海堤的整体抗滑稳定性是整个围海工程顺利完成的关键。针对目前常采用的瑞典条分法与简化毕肖普法整体抗滑稳定计算方法,考虑孔隙水压力的影响,从基本公式、基本假定、公式推导、公式简化等方面对瑞典条分法和简化毕肖普法进行了对比并得到了两种方法的之间的相互关系。结合福建省沿海软基筑堤典型工程,分别用这两种计算方法得出稳定系数,进一步论证了两种方法之间的相互关系。A seawall is the main subject of the coastal reclamation, and the accurate calculation and the control of the overall sliding stability of the seawall are the key points of the successful completion of the whole reclamation projects.The Sweden slice method and the simplified Bishop method are two overall anti-sliding stability calculation methods which are commonly used at present.Considering the influence of pore water pressure, these two methods are compared from the aspects of the calculation principle, the basic assumption, the derivation and simplification of formula and so on, and the relationship between two methods is obtained.Then a typical project of soft embankment along the coast of Fujian province is calculated using these two methods, further demonstrating the relationship between the two methods.
