摘　　要：在空间受限的施工环境下,先施工一定体积现浇混凝土结构,再采用顶升技术和精确定位技术均匀顶起混凝土结构至设计高度,托换完成后进行永久结构施工。该技术能有效地避免对原有结构拆除,节约成本,能在保证大体积混凝土结构施工质量的同时,使经济效益最大化。In the construction environment with limited space,a certain volume of cast-in-place concrete structure was constructed first,and then the jacking technology and precise positioning technology were used to uniformly lift the concrete structure to the design height.After the replacement was completed,the permanent structure will be constructed.This technology can effectively avoid the demolition of the original structure,save the cost,and maximize the economic benefit while ensuring the construction quality of the mass concrete structure.
