历史悠久的岩石灯塔在危险珊瑚礁周围的安全航行中发挥着至关重要的作用。然而，它们的寿命受到海浪的冲击的威胁。 GPS 等虚拟导航设备很容易出错，依赖它们可能会带来灾难性的后果。因此，水手们将继续需要这些战略结构的物理视觉辅助。在对特定地点的极端波浪进行表征后，该研究通过经过验证的有限元数值模型评估了 Fastnet Lighthouse 在不同波浪载荷作用下的动态响应。该研究的目的是为此类结构提供全面的生存能力评估方法。
Historic rock-mounted lighthouses play a vital role in the safe navigation around perilous reefs. However their longevity is threatened by the battering of waves. Virtual navigational aids such as GPS are fallible, and reliance on them can be disastrous. Mariners will therefore continue to need the physical visual aids of these strategic structures. After a site-specific extreme wave characterisation, the study evaluates the dynamic response of Fastnet Lighthouse under the action of different wave loadings through a validated FEM numerical model. The aim of the study is to provide a comprehensive survivability assessment methodology for this type of structures.
