溢洪道弧形工作门设计过程中几个空间角度的探讨

The Research on Some Space Angle during Designing Spillway Radial Gate

介绍了潘口水电站溢洪道弧形工作闸门斜支臂设计过程中的几个空间角度问题。其中主要包括支腿偏斜角、支臂偏斜角的区别、计算及现行规范中空间扭角公式的推导,并简要阐述了支臂和门叶对接过程中可能遇到的问题。弄清这几个空间角度能为减小闸门制造和安装误差提供一定的理论依据。

Several problems about space angle in designing oblique supporting arm of spillway radial gate of Pankou Hy-dropower Station are introduced, including the differences the offset angles of supporting leg and supporting arm, calculation and derivation on formula of torsion angle in current specification. The problem in the process of jointing supporting arm and gate leaf is briefly presented. Understanding space angle can provide theoretical foundation for reducing deviation on gate manufacturing and installation.
