Abstract

The large aqueduct has the characteristics of large streamflow, heavy load and complicated structure and so on. Different from the high dams, most of the aqueducts are constructed with the thin-walled concrete structures. When analyzing the structure of the aqueduct, people often only consider that after the completion of the overall project, whether the aqueduct meets the design requirements or not, ignoring the large thin-wall aqueduct deformation and stress distribution under different working conditions during the construction period, and other construction technical issues that may emerge. It is not so clear whether the prestressed tension load classification and tensioning sequence changes may significantly affect the aqueduct structure system. Therefore, further study is needed. Under the premise of ensuring the safety of the aqueduct structure and the convenient construction, this paper puts forward a feasible plan of three hierarchical tensioning of prestressed steel strand and the suitable release time of the aqueduct body weight, providing the theoretical and technical support for the similar large three-way prestressed aqueduct and hydraulic structure construction.
