某船厂船坞设计关键技术

Key design technology of dock for a shipyard project

浙江某船厂船坞工程是废除现有船坞新建2座船坞的改扩建项目,工程建设规模不大,但环境条件和自然条件复杂,尤其是坞口区域建设条件极差,技术难度大。设计围绕水上基坑建造坞口、坞墙结构、船坞止水、高灵敏土地基加固等一系列关键技术问题进行研究,研究成果可为在有限岸线和狭窄空间以及复杂地质海洋环境条件下建造船坞时提供借鉴和参考。

A shipyard reconstruction project with two parallel ship building and repair yards based on abolition of the existing docks is the core facilities for production and development of the factory. The natural circumstances and environmental conditions are very complicated, especially the docking port area construction, which is in very disadvantageous conditions, and with tremendous technical difficulties. The design is focused on the research of some key technical problems, including design around dock-entrance building within a waterfront deep foundation pit excavation, earth-retaining structures, water-sealing in dock, and high-sensitive soft subsoil reclamation. This project can be used as reference and guidance for the construction of docks under a limited shoreline or a narrow space with complex geological conditions.
