不对称闸墙双铰底板式闸室结构仿真分析

以四川省青居船闸工程为背景，分别采用平面简化法和有限元法对闸室结构进行内力计算，并同原型观测数据进行对比分析，结果显示：简化法较难满足不对称闸墙双铰底板式船闸结构计算的需要，而基于非线性有限元法的计算成果与结构的真实受力状态吻合较好，能反映船闸结构内部最不利的位置、受力状态及其变化规律。

Simulation analysis of ship locks with double-hinged soleplate and asymmetric lock wall

Taking the Qingju ship lock project in Sichuan province as the background, this paper calculates the inner force of lock chamber structure by Plane Simplified Method and Finite Element Method, and carries out an analysis on the prototype observation data, which shows that the Plane Simplified Method is difficult to meet the need of calculation for asymmetric gate double wall floor type reaming of ship lock structures, while the calculation results based on the nonlinear finite element method tallies better with the real stress state. Moreover, it can reflect the most unfavorable position of internal ship lock structures, stress state and the changing laws, and the results may serve as reference for the engineering design of the ship lock.
