近年来,人们对船闸人字闸门的门体刚度或抗扭刚度的兴趣不断增加。随着闸门高度的增大,加大闸门的抗扭刚度以承受作用于闸门上的死荷重,瞬时荷载或雍水荷载已成为设计中特别关注的问题。 美国的一个船闸人字闸门计算机辅助设计门题小组,曾经研究了各种影响大型人字闸门抗扭刚度的方法与途径,利用有限单元法计算机模型分析了某些运行中的大型人字闸门(如单扇门叶27.13米高,18.9米宽)的刚度。专题小组还研究了取
In recent years, there has been an increasing interest in the door body stiffness or torsional stiffness of the Miter Gate. As the height of the gate increases, increasing the torsional stiffness of the gate to withstand the dead load, instantaneous load or Yong water load acting on the gate has become a particular concern in design. A US shiplock gable gate computer aided design topic group, has studied a variety of methods and ways of affecting the torsional stiffness of large gable gate, the use of finite element method computer model analysis of some of the operation of the large gantry gate ( Such as single door leaf 27.13 meters high, 18.9 meters wide) stiffness. The task force also studied
