摘要: 平面钢闸门是水利工程的核心建筑物，在运行中存在振动变形等问题。本文依据实际工程，采用相邻间距和之半法分析多主梁的线荷载，使用组合截面法对各构件进行理论计算，并针对现有研究因结构简化导致对约束等效施加问题，考虑主轮对整体结构的影响，建立完整三维模型，对单侧挡水时的平面定轮钢闸门进行有限元仿真，研究在最高挡水位时各构件的应力应变，与理论分析和相关规范做对比，为闸门的强度校核与优化设计提供参考。并圈起水域，基于流固耦合定义声学与物理区域，展开湿模态分析，研究闸门在挡水时的振动规律与响应特性，以保障平面钢闸门在复杂水力环境中的安全稳定运行。

Abstract: The plane steel gate is an essential component in hydraulic engineering, but it encounters vibration and deformation issues during operation. This study analyzes the line load of multi-main beams in a real project using the method of halves of the sum of adjacent distances. The combined section method performs theoretical calculations for each member. To address the problem of imposing constraint equivalence due to structural simplifications in previous studies, while considering the influence of the main wheel on the overall structure, a comprehensive 3D model has been established. Finite element simulation is conducted on plane fixed-wheel steel gates for single-side water retainers, studying the stress-strain in each part at the maximum water level. By comparing with the theoretical analysis and related specifications, it provides a reference for the strength check and optimized design of the gate. In addition, circle the water area, define acoustic and physical regions based on fluid-structure coupling, and develop wet mode analysis. Studying the vibration regulation and response characteristics of gates when holding back water to ensure safe and stable operation of plane steel gates in complex hydraulic environments.
