崖门口外围垦与潮汐水道稳定性分析及数值计算

Stability Analysis and Numerical Calculation for Tidal Inlet with Reclamation at Yamen Outlet

提出了河口围垦工程二维流场计算与上游河网一维计算联网的整体数学模型，解决了二维计算中围垦工程对口门边界水流的反馈影响．结合崖门出海航道围垦工程方案的数值计算，将Ｐ—Ａ关系用于口外围垦与通航水道的稳定性分析中，对围垦工程可能对出海航道产生的作用和影响进行了具体的计算分析预测．

An integral numerical model combined with two dimensional model for the sea side and one dimensional model forth river network has been develped to solve the back scatter influence due to the reclamation near the Yamen outlet of the sea side. With the mathematical calculation for the reclatation project on the Yamen sea going channel, the P-A relationship is applied in the stability analysis of the navigation channel and the influence is predicted for the reclamation on the channel.
