宝钢马迹山港扩建卸船码头涨潮时水流与码头前沿存在20°左右夹角，对船舶靠泊有较大影响．通过物理模型试验，比较分析了多个方案的整治效果，结果表明，设置一定长度的导流堤可有效改善扩建卸船码头前水流流态，并推荐东导流堤150m方案．推荐方案实施后，现场水文测量资料分析表明，工程实施后的水流流态与模型试验结果完全一致，明显改善了扩建卸船码头前沿的水流条件，涨潮时水流与码头前沿夹角平均为5°～10°，基本归顺了码头前沿水流．

英文摘要：

There is a angle of about 20 degrees between the port and the flood flow along the extended Majishan unloading harbor in Bao Steel, which affects the berthing of ships. Based on the physical model experiments of several projects, the diversion dike arranged will improve the tidal current along the unloading harbor, and the project of 150 m-long east-diversion dike is thus suggested. Analysis of the local data measured shows that the flow condition keeps consistent with the result of the physical model after the project, that the angle between the port and the flood flow is 5 - 10 degrees, and that the diversion dike improves the tidal current along the port.
