摘要: 围堰是保证涉水工程干地施工的重要建筑物。在水力等外界因素作用下，其运行机制复杂。为有效反映渗流作用对围堰安全的影响，以某码头工程的围堰为例，对其安全性进行数值模拟。通过对围堰渗流场和应力场进行耦合分析和研究，计算其应力、位移、安全系数等相关参数。研究表明，流固耦合作用的计算结果有利于保证围堰的设计安全。

Abstract: Cofferdam is the important building to ensure the wading engineering performed in the dry land.Under the influence of external factors such as hydraulic power，its running mechanism is complex.In order to effectively reflect the influence of seepage effect on cofferdam safety，this paper takes the cofferdam of some dock project for example，and processes the numerical simulation on its safety.It calculates the related parameters such as stress，displacement and safety coefficient by coupling analysis and research of the cofferdam seepage field and stress field.Study shows that the calculation result of fluid-structure interaction is helpful to ensure the safety of the cofferdam design.
