Optimization Design and Application of Sluice Pier Sliding Formwork

The sliding formwork, combining high efficiency and low cost, is a kind of advanced technology in the construction of sluice pier of hydropower projects. Number of jacks and elevating shelf spacing are two important parameters in the structure design of sliding formwork, the mathematical model of the relationship between manufacture costs and jack number, spacing between the elevating shelf was established using polynomial least square method, the best value of jack number and spacing between the elevating shelf were calculated by using the simulated annealing algorithm, thereby optimized the design parameters of sliding formwork structure, whilst expatiated the technology of installing, debugging, sliding and disassembly of sliding formwork, put forward the feasible methods for solving the problems that often appeared in the construction of sliding formwork, summed up the merits of sliding formwork, analyzed the technology and economical benefit of sliding formwork
