摘要
本文讨论了大型人字门背拉杆的预应力方案及其分析方法,并针对几种不同门型,详细研究比较了它们的抗扭刚度、用钢量和用钢效率.研究成果为大型船闸人字门的设计提供了可靠的理论基础.
In this paper,the prestressing scheme of back diagonals of large miter gates and its analysis technique are discussed,and in connection with some conventional types of miter gates,the torsional stiffness,steel consumption and usage factors are investigated and compared.The results provide a reliable theoretical basis for the design of miter gates of large ship locks.
