Stability Calculation Methods for the Cylinderical Caisson Breakwater

The cylinderical caisson breakwater is a new type of breakwater on soft clay.This paper established 3 stability calculation methods for the cylinderical caisson breakwater:The finite element analysis,the numerical limit simulation method and the simplified limit equilibrium method.The features of 3 calculation methods are compared in this paper,And that is the foundation for the structure optimization of the breakwater extension project in Tianjin Harbour.
