针对水电站厂房中复杂结构的布筋难题,提出了蜗壳及尾水管渐变段曲面三维布筋的实现方法. 对混凝土渐变段轴向钢筋采用基于放样的离散法来构造. 根据环向钢筋离散点的曲率大小,分别选用直线、圆弧及样条曲线来拟合,其中重点介绍了曲率计算及不同线型的拟合方法. 在此基础上开发了能用于蜗壳及尾水管布筋设计的三维CAD系统. 该系统具有三维钢筋创建及二维施工图和信息表生成功能,显著提高了复杂结构的图纸质量和设计效率.

Aiming at the difficulties in the layout of reinforcing bars of complicated structures of hydropower stations, a realiza-tion methodology for three-dimensional layout of reinforcing bars in transition section of spiral case and tailrace conduit of hydro-power station is proposed. The discrete method on the basis of lofting is used to generate the layout form of axial reinforcing bars in the concrete, and then the straight line, arc and spline curves are adopted to fit the bars according to the curvature of discrete points of circular bars. The fitting methods of various curve types as well as curvature calculation are mainly introduced. Based on the results, a three-dimensional reinforcing bars design CAD system for spiral case and tailrace conduit is developed, which im-proves the quality and design efficiency of the complex structure.
