摘　　要：南流江出海口海堤经过长期海浪冲刷,结构逐渐老化,为保障其安全,开展海堤标准化建设。以南流江北海市合浦县党江镇段南域海堤为例,按照因地制宜、就地取材的原则进行海堤加固,并根据堤段所在的地理位置、重要程度、堤址地质条件、筑堤材料及风浪特性、施工条件、运行管理要求以及工程造价等因素选定各个堤段的加固方案。根据选定的南域海堤标准化加固方案,工程建成后可减轻南域海堤内洪灾损失,使海堤达到防御南流江及潮水20年一遇的防洪标准,为类似海堤加固措施选取提供新的设计思路与方案选择方法。The structure of the seawall at the estuary of Nanliu River is gradually aging after a long-term wave erosion. In order to ensure its safety while implementing standardization of seawall. Taking Nanyu seawall of Nanliu River at Dangjiang Town of Hepu County, Beihai City as example, reinforcement schemes of various embankment sections were designed in accordance with the principle of adapting measures to local conditions and local materials, and taking into account the geographical location, importance, geological conditions, dyke materials, characteristics of wind wave, construction conditions, operation management and construction cost. After all embankment sections of Nanyu seawall are reinforced according to the selected standardized schemes, it will be able to alleviate flood losses and resist 20-year recurrence flood of Nanliu River or tide.
