| Abstract: | According to the construction experience and the characteristics of the aqueduct 1 ~2 at Chang fiver main ca- nal, the construction mode of bailey beam supporting structure body while concrete pouring was advanced. By uniform loading on the bailey beam to test aqueduct deflection, water filling test on pre-arch and ANSYS simulation, result was gotten that the strength of bailey beam can meet the construction requirements, and pre-arch would protect the bottom plate of the aqueduct against deformation. This construction method was economical and feasible, worthy reference. |
