本文针对传统变幅式打桩船在复杂海域工况下，作业效率低、定位精度低、适应性差等方面进行深入分析，结合旋转式打桩船整体设计与沉桩工艺研究；同时通过详细分析不同工况下锚泊力、耐波性计算分析，以及在梅山港、台州联岛等大型水工项目沉桩施工案例，验证旋转式打桩船在沉桩功效上提高40%，沉桩定位达到厘米级，适应海况比传统变幅式打桩船扩展30%，且在狭窄水域、老码头改造、跳桩施工等具备显著优势。
This study conducts an in-depth analysis of traditional amplitude-type pile-driving vessels under complex marine conditions, addressing their limitations in operational efficiency, positioning accuracy, and adaptability. By integrating research on the overall design and pile-driving techniques of rotary pile-driving vessels, the analysis further examines anchoring force and wave resistance under various operational scenarios. Case studies from large-scale hydraulic engineering projects, including Meishan Port and Taizhou Lian Island, demonstrate that rotary pile-driving vessels achieve a 40% improvement in pile-driving efficiency, with positioning accuracy reaching centimeter-level precision. Their adaptability to sea conditions exceeds traditional amplitude-type vessels by 30%, offering significant advantages in narrow waters, old wharf renovations, and pile-jumping operations.
