港口工程深水大潮差下砂芯防波堤断面比选

Comparison and selection of deep water sand-core breakwater sections for port engineering in high tidal range water

针对港口工程传统抛石斜坡堤结构深水大潮差条件下堤心石用量大的问题,进行了深水砂芯斜坡式防波堤研究。结合某实际工程项目中砂芯防波堤断面的比选,主要从断面结构选择、施工可行性、工程造价和潮差作用下的边坡稳定性等方面对各个方案进行对比分析。结果表明,砂芯防波堤断面采用块石围埝方案满足港口工程深水大潮差条件下的设计要求,该结构形式防波堤断面为港口工程深水防波堤或石料缺乏地区的类似工程提供借鉴和参考。

In order to reduce the quarry-run quantities of traditional sloping riprap,a research about deep water sand-core breakwater has been conducted.Based on the optimization design process of the cross section of sand-core breakwater in a practical engineering project,a comparative analysis has been adopted among design section selection,construction feasibility,cost and overall stability under high tidal range.The results show that the sand-core breakwater sections with rock bund can fulfill the project design requirements under the high tidal range conditions,and the conclusion can provide a reference for the similar projects.
