摘要
箱筒型基础防波堤是一种软基上的新型防波堤。针对其断面稳定性的分析建立了三类计算方法:有限元分析方法、数值极限平衡分析方法和简化极限平衡分析方法;对三类计算方法的特点进行了比较,并以此对天津港南北防波堤延伸工程的箱筒型基础防波堤结构进行了优化。
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.
