蜗壳及尾水管复杂空间曲面三维布筋方法及应用
Application of three-dimensional reinforced bar arrangement method for complex space surface of spiral case and tailrace conduit
摘要
Abstract
The spiral case and tailrace conduit in hydropower stations are constituted of complex space surfaces and the struc-ture is extremely complicated. Thus the reinforced bar design under two-dimensional environment is labor and time consuming. According to the above problems, considering the shape of reinforced bar and the concrete surface is similar, the lateral reinforce-ment design based on sectional method and axial reinforcement design based on discrete reconstruction method are presented re-spectively aiming at the curved transition section, based on the thought of "three-dimensional reinforcement design, two-di-mensional drawing". The engineering practices show that the presented methods could realize three-dimensional reinforcement design of spiral case and tailrace conduit with high efficiency and good drawing quality and it has reference for other reinforcement design of structures with complex shape.关键词
