摘要
基于三峡多级船闸人字门提出了背拉杆预应力设计计算的一种方法—“有限元法—力法”分析方案，据此讨论了两种不同的背拉杆预应力施加方法，还比较了不同构造形式的门型的抗扭刚度。
Concerning the miter gate of the Three Gorges Multichamber Lock, the back drag rod prestress design & calculation method—“limite-element method—Mechanics method”is advanced Based on this, the method of exerting prestress on two different kinds of back rods is discussed and the gate type and anti-twisting rigidity of different structural types is compared, providing reference to design analysis of anti-twisting property of large miter gate
