摘要
钢闸门是挡水与泄水建筑物的重要组成部分,钢闸门的安全与否直接关系到水库下游群众的生命财产安全;由于钢闸门是空间结构,很难实现手算,因此传统的计算方法一贯是将钢闸门简化为平面结构再进行计算,这种计算方法精度不足。有限单元法作为一种新兴的工具,能够实现较精确的计算分析。文章探讨了如何利用有限元对钢闸门进行建模、静力学分析,并和传统的计算方法行进对比。
The steel gate is an important composition of water retaining and drainage building, whether the steel gate is safe relates directly to the life and property safety of the mass living at the downstream of the reservoir. Hand computation is difficult to be realized because the steel gate belongs to the spatial structure, the steel gate is always simplified as a planar structure and then calculated in the traditional computation method, and this calculation method is not accurate enough. As a kind of new tool, the limited unit method is capable to achieve more accurate calculation and analysis. The paper discusses how to use finite elements to construct model and conduct statistic analysis for the steel gate and compare with the traditional computation method.
