闸站结合工程位移有限元分析研究

Analysis and Research on Displacement of Sluice-station Incorporation Engineering by Using FEM

以裴家圩枢纽的工程为例,采用三维有限元分析软件MSC.MARC分析闸站结合工程在各荷载作用下所产生的位移。根据计算结果可知,节制闸和泵站在各工况下的位移较小,其整体稳定性较好,工作性态安全。分析表明,三维有限元分析能较直观、准确反映闸站结合工程的位移状况,是解决复杂空间结构问题的有效方法。

Taking the engineering of Peijiawei Hydro Project for example, the 3D FEM software （MSC. MARC） is used here to analyze the displacement of the sluice-station incorporation engineering under each load combination. Acco^ing to the calculation results, it is found that under various working conditions, the sluice and pumping station would generate relatively small displacement, thus with good overall stability and safe working behaviour. The analysis indicates that the 3D FEM is the effective way to solve complex space structure problems, which could reflect the displacement of the sluice-station incorporation engineering intuitively and accurately.
