摘要
针对普通平面钢闸门需要高大排架柱这个问题,以某大型拦河水闸为例,分析了大型平面钢闸门的新型升降技术,并利用有限元软件ABAQUS对闸门在不同工况下受到最大启闭力时进行荷载优化分析,对比分析了闸门采用新型升降技术和采用普通的启闭技术时的位移和应力值。结果表明:采用新型升降技术的位移和应力在各工况下都要小于普通的启闭技术,采用普通启闭技术的最大位移和应力主要分布在排架上,不利于闸室整体稳定性和抗震,采用新型升降技术的最大位移和应力主要分布在闸墩上,受力布局合理,提高了结构的抗震能力,并具有良好的景观效果。
In view of the problem in the lifting of normal plane steel gates needing tall column of frame,a large river sluice gate is taken as an example to study the new lifting technology of large plane steel gate.The load analysis of sluice gate structures with new lifting device are carried out by finite element software ABAQUS under different operating conditions with maximum lifting forces,and the displacements and stresses of gate structure using new and ordinary lifting technologies are compared and analyzed.The result shows that the displacement and stress of gate using new lifting technology are less than that using ordinary lifting technology under each operating conditions.The maximum displacement and stress when using ordinary lifting technology mainly distribute on frame which is not conducive to the overall stability and aseismic capacity of lock chamber,while those when using new lifting technology mostly distribute on sluice pier and the force distribution is also reasonable which is conducive to the improvement of aseismic capacity of gate structure and landscaping effect.
