结合ABAQUS大型有限元分析软件，以某分离式船闸的标准段闸室为基本计算结构，并拟定地基模拟范围，建立了闸室的三维有限元计算模型，分析了在不同工况下的应力分布规律和变形特点。并根据三维有限元内力计算原理及方法计算出闸室段各部位控制点的内力，为设计人员进行配筋设计提供了便利条件。

The large-scale finite element analysis software ABAQUS was used to develop a three-dimensional finite element model of the lock chamber based on the basic calculation structure of standard section of lock chamber in a separate shiplock and the simulation scale of foundation. The model can be used to analyze the stress distribution and deformation characteristics under different working conditions. The internal forces at the controlling points of each part of lock chamber were calculated based on the principle of three-dimensional internal force calculation, which can provide the convenient conditions for reinforcement design.
