在韩国南部建造了一座浮动防波堤。四个独立的浮式防波堤单元系泊到十个深埋的嵌入式吸力锚。埋入式吸力锚是一种通过吸力桩安装的永久性海上基础。嵌入式吸力锚的横截面为圆形，其直径等于用于将其打入海底的吸力桩的直径。通常沿圆周沿着添加垂直凸缘以增加其阻力。介绍了吸力锚承载力和尺寸的确定。还讨论了预埋吸力锚的施工和安装细节，以及现场验证试验结果。共制造并安装了10个钢嵌式吸力锚。嵌入式吸力锚的安装是通过将吸力桩连接到其顶部来完成的。随后的验证试验验证了嵌入式吸力锚的设计承载能力。建造了一个由四个独立单元组成的浮式防波堤。最初，嵌入式自重混凝土块被认为是摩尔浮动防波堤单元。然而，后来，由于许多环境限制，嵌入式吸力锚取代了混凝土块锚。每个漂浮单元用四个嵌入式吸力锚进行锚定。现场验证试验表明，嵌入式吸力锚可以提供必要的阻力，对预期的风和波浪力。
A floating breakwater was built in Southern Korea. Four separate floating breakwater units were moored to ten deeply buried embedded suction anchors. The embedded suction anchor is a type of permanent offshore foundation installed by a suction pile. The cross section of the embedded suction anchor is circular, with its diameter being equal to that of the suction pile that is used to drive it into the seafloor. Vertical flanges are typically added along the circumference to increase its resistance. Determination of the loading capacity and the dimensions of embedded suction anchors are described. Details of the construction and installation of embedded suction anchors, as well as the field proof test results are also discussed. A total of ten steel embedded suction anchors were manufactured and installed successfully. Installation of embedded suction anchors was accomplished with a suction pile attached to its top. Subsequent proof tests validated the design loading capacity of embedded suction anchors. A floating breakwater consisted of four separate units was constructed. Initially, embedded deadweight concrete blocks were considered to moor the floating breakwater units. Later, however, embedded suction anchors replaced the concrete block anchors due to numerous environmental constraints. Each fioating unit was anchored with four embedded suction anchors. Field proof tests indicate that the embedded suction anchors can provide necessary resistance against the anticipated wind and wave forces.
