水电站蜗壳及尾水管由复杂空间曲面构成，体型结构十分复杂，二维配筋设计工作量大，效率低。基于“三维配筋设计、二维出图”的设计思想，根据蜗壳及尾水管空间曲面特征及配筋特点，考虑到布筋形状与混凝土结构面具有相似性这一特点，对曲面渐变段提出基于截面法的横向布筋方法及基于离散重构法的纵向布筋方法。工程实例表明，该方法可实现蜗壳及尾水管复杂空间曲面三维配筋设计，可有效提高设计效率和出图质量。可为复杂体型结构三维布筋设计提供参考。

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.
