| 摘 要： | 针对钢管桩、预应力钢筋混凝土大管桩及PHC桩在海水中容易遭受氯离子侵蚀、耐久性差、难以满足海洋工程100~120 a高耐久性服役寿命要求的问题,介绍了玻璃钢包覆防腐在桩基工程中的应用。采用玻璃钢对桩基础进行包覆是一项行之有效的附加防腐蚀措施,2 mm左右包覆厚度的玻璃钢就具有50 a以上的抗氯离子渗透寿命,能显著提高桩基础的耐久性,满足海洋工程结构100~120 a设计服役寿命的要求。

| Abstract: | For the Yangtze River Estuary area in recent years,some new reclamation projects cannot excavate the storage pit because of constraints or cost control.Through Changxing submerged breakwater engineering construction,we introduce the construction technology for integration of deep-water channel dredging and filling in the Yangtze River Estuary,and discuss the key technologies of dredging,anchoring and bowing.The construction technology does not need to set the storage pit,and the dredging soil could be pumped to the shore for land reclamation.It is very effective,resulting in a comprehensive benefit in the Yangtze River Estuary area. |
