大连长兴岛建港条件研究

摘要

采用自然条件分析、岸滩演变分析、马家浅滩成因及稳定性分析，以及泥沙回淤与骤淤积计算、设计波浪计算、流场及其变化计算等手段，对大连长兴岛北港区（马家咀至高脑子角）建设深水大港条件进行了探讨。研究和分析结果表明，从水动力泥沙角度考虑，大连长兴岛北港区具备建设30万吨级大港的良好条件。%By means of analysis of natural conditions, beach evolution and cause and stability of Majia Shoal,and computa-tion of sedimentation and sudden sedimentation, design wave, tidal current field and its change,deepwater port constructing conditions of Changxing Island from Majiazui to Gaonaozijiao in Dalian are discussed. The study and analysis results show that the north harbor of Changxing Island possesses favorable conditions to be constructed into 300 000 DWT harbor from the point of view of hydrodynamics and sediment.
