为了研究二维潮流数值模拟中桩基的影响 ,导出了二维潮流桩基数模控制方程组 ,建立了桩基的二维潮流数值水槽 ,利用物模试验得出的桩基摩阻系数和桩基附加糙率 ,并经水深修正后 ,对洋山港一期工程桩基码头的潮流情况进行了模拟计算 ,数值模拟结果与水槽试验结果非常一致。为桩基二维潮流数值模拟技术提供了应用基础和可操作方法。

In order to study the influence on pile founda tion in the numerical Simulation of two dinensional tidal flow,the governing set of equations for numerical model of two dimensional tidal flow with pile foundation have been induced,and the numerical water flume of two dimensional tidal flow for pile foundation has been built.And then,with an adjusted friction coefficient and an additional roughness coefficient of the pile foundation from some physical model tests,the tidal flow field has been simulated,which was about a piled wharf of the first phase project in Yangshan Port.It indicated that the results from this numerical simulation were very close to some from water flume tests in laboratory.So some applied foundation and operational methods about the two tidal flow simulation technology for some pile foundation have been provided.
