The structure of pile-supported pier is quite common in the construction of bridges,wharves,and other structures,and its construction is relatively difficult.The cost control of various measures is one of the factors that construction units consider first.On the basis of the project of 18# to 20# berths in Zhangwan working area of Sandu Bay area of Fuzhou Port,the original design scheme of the bottom formwork supporting structure of the substation platform for this project is optimized,and the construction organization is adjusted.The consumption of supporting steel is reduced when the bearing capacity of the support structure is ensured.Finally,the substation platform is successfully cast in the project and passed the acceptance,saving construction costs of 813,000 yuan.
