摘要
船闸中的人字闸门承受较大的扭矩,为了增加门页的抗扭刚度,普通配有背斜杆。无论是预应力还是非预应力的背斜杆,我国至今还没有一个公认的比较简单合理的计算方法。为此,作者在研究了一些有关资料和实验成果之后,从探讨人字门背斜杆门页的抗扭作用入手,建立简捷可靠的背斜杆计算公式,供工程设计参考使用。
The miter gate of a lock is constantly subject to a stroug torgue, and for the purpose of resisting this torsional force, diagonal members are always fixed on the back of miter gate. But till now, there are no simple and reaso nable computation methods recognized by common being used in the design papers, whether the members are of prestressed or non-prestressed. For this reason, after studying a lot of reference materials and relevant experimental results the authors give out a simple and reliable computing formula for use of design works. It may be of help to those who are devoted to this work.
