装卸式防汛墙在波浪作用下的变形分析

为计算分析新型装卸式防汛墙在波浪作用下的变形挠度、校核其安全性能,基于推板造波机理论,利用CFD商业软件FLUENT二次开发建立二维数值波浪水槽模型模拟数值波浪,并通过有限元分析软件ANSYS现有接口程序导入FLUENT波浪荷载,获得了波浪荷载沿防汛墙断面分布、防汛墙在波浪作用下的位移分布及变形挠度曲线。结果表明,波浪形态较好,荷载分布合理,为装卸式防汛墙的设计和运行提供了参考依据。

Deformation Analysis of Disassemble Flood Control Wall under Wave Action

In order to analyze the deformation and deflection of new-type disassemble flood control wall under wave action and check safety performance,based on the theory of push plate wave maker,two-dimensional numerical wave channel model is established by using FLUENT secondary development function in CFD commercial software.And the distribution of numerical wave is simulated.Then the displacement distribution and deflection curves of flood control wall under wave action can be got by the import of FLUENT wave load to FEM software ANSYS based on the existing interface program.The results show that the wave shape of numerical wave is good and the load distribution is reasonable,which provides reference for design and operation of disassemble flood control wall.
