| 摘 要： | 采用有限元方法建立了二维平面水流模型，并引入驻点的概念模拟水中桩柱对水流的影响，即在计算中将网格节点设置于桩柱处，并在该节点设置滞流边界条件，即流速为0m／s．以长寿朱家坝码头的高桩码头方案为算例进行了模拟计算，结果表明该方法可以较好地模拟桩群对水流流速、流态的影响．

| Abstract: | This paper constructs a two-dimension plane flow model with finite element method, and introduces the concept of stagnation node to simulate the influence of pile groups on flows. Namely, the node of grid is located where there is a pile and the stagnation boundary condition is set on the node, which means that both the x and y velocity components are set to zero at the specified nodes. This paper takes the highpile wharf scheme of Zhujiaba in Changshou as an example to execute simulation computation. The result shows that the method can preferably simulate flow velocity and pattern of flow which is influenced by pile groups. |
