Optimization design study on prestressed aqueduct body structure of reactive powder concrete
As an important part of lifeline engineering, the aqueduct plays import role of not only in transmitting water but also in flood discharge and diversion works. In this paper, the reactive powder concrete (RPC) is used in the study of optimal design for aqueduct body structure in order to solve the safety running problem for current normal concrete prestressed aqueduct. The optimal model of RPC200 prestressed aqueduct body is established by using structure optimization theory. In the optimization design, the lowest cost of aqueduct body is taken as the object function, and the thickness of the sidewall and bottom board as well as the area of the prestressed reinforcement are used as design variables, and the strength and deflection of the aqueduct body are taken as the constraint conditions. The optimal analysis models of finite element for the aqueduct body with 32 m span is established. For the different ratios of depth to width of aqueduct body, the optimal calculation studies are carried out by considering both RPC aqueduct bodies without prestressed reinforcements and the aqueduct bodies with prestressed reinforcements in the bottom board respectively. Some valuable conclusions are obtained which can provide important references for the engineering applications.
