摘要
嘉兴电厂二期取水工程位于海象条件异常复杂的杭州湾海域,工程采用海上浮运沉放的工艺进行施工,其中取水头为外径25m,高16.6m,空气中重约4700T的圆桶形结构,结构偏心、重心高、稳定性差,对海上浮运沉放施工极为不利。针对取水头起浮、海上浮运和加水下沉的各个阶段的进行稳定性分析,为确定最优的吊沉方案,确保取水头精确就位提供理论依据,成果也可为其它类似工程提供借鉴与参考。
Water intake project of Jiaxing 2^nd stage power plant is located in Hangzhou bay which ocean condition is very severe. The project is constructed with immerse concrete tube method, and the water intake caisson is a barrel type structure with 25m diameter, 16.6m height and approximately 4700 ton weight, the floating and sinking construction is so difficult because of stability problems. The stability analysis for different stages of floating and sinking prouides the scientific basis for optimize the sinking scheme and assure the locating precision of water intake caisson, and offers the references for other similar projects.
