| 摘要: |
| 通过对平面人宇闸门主横梁受力特点、结构特征及内力、应力分布规律的分析，提出了人字闸门主横梁应为拆线式变截面梁；并用实例从主横梁内力、应力的分布及强度、刚度、局部稳定性、经济合理性等方面，阐述了折线式人字闸门的优越性。 |

| Abstract: |
| The reasonable type of main cross beams in plain mitre gate should be nonuniform and broken-line in form was proposed in this paper by analysing the character of beam stress.structure,distribution of internal force and siress.In addition,the advantage of such gate was demonstrated with an actual example from many parts such as the distribution of internal force,stress,intensity,rigidity,local stability,economic advisability and so on. |
| Key words: mitre gate,internal force,deformation, analysis |
