摘　　要：水位变动区的桩-墩结构在当前的码头、栈桥、桥梁等结构物的建造中十分常见,其施工受水位变化影响较大,难度和成本均较高。依托惠州市大亚湾石化区内某重件码头工程,对工程中的入水墩台施工提出了一种可广泛适用的方法——反吊底模施工方法。该方法无需围堰作业即可创造干地施工条件,具有经济性好、施工效率高、施工难度低等优点。经方案设计以及荷载验算,验证反吊底模施工理论上可行,并最终在所涉工程的入水墩台施工中取得了良好的效果。Pile-pier structures in water level fluctuation zone are very common in the current construction of wharves,trestles,bridges and other structures,and their construction is greatly affected by water level changes,the difficulties and costs are high.Based on the project of a heavy loading wharf in Daya Bay Petrochemical Zone of Huizhou City,a widely applicable method for the construction of partially submerged piers,the reverse lifting base mould construction method,has been proposed.This method can create dryland construction conditions without cofferdam work,which has the advantages of low cost,high construction efficiency and low construction difficulty.Through scheme design and load calculation,it is verified that the reverse lifting base mould construction method is feasible theorectially,and finally good results were achieved in the construction of the partially submerged pier of the project involved.
