非对称工况下双线船闸不同施工工艺对结构的影响

Influence of different construction processes on structure of double-lane lock under asymmetric working condition

随着水运事业的发展,双线船闸已越来越多的使用在内河航道中,不同的施工过程对船闸应力产生不同的影响,而合理确定船闸结构应力是保证船闸系统稳定和安全的关键。本文使用有限元分析软件,依托于海安船闸建立了非对称工况下双线船闸有限元计算模型,分析不同施工顺序下闸首和闸室的应力分布规律及变形特性。结果表明:不同施工顺序闸首和闸室应力存在空间上的差异性,表现为靠近船闸中心线差异明显,向两侧逐渐消弱。

With the development of water transport, double-lane lock has been widely used in inland waterway. Different construction processes of ship locks have different impacts on the stress, and reasonable lock structure＇s stress is the key to guarantee stable and safe lock system. This article uses finite element analysis software to establish the finite element calculation model of double-lane lock under asymmetric conditions relying on Hal＇ an lock, the characteristics of stress distribution and deformation of lock head and lock chamber under different construction sequence are analyzed. Results show that the differences of stress of lock head and lock chamber under different construction sequences exist on the space, and the difference is apparent close to the center line of the ship lock, and is weakened to both sides gradually.
