大跨度桁架平面闸门静动力特性分析

Static and Dynamic Characteristics Analysis of Large Span Truss Gate

随着我国水利事业的发展,大跨度桁架平面闸门的应用越来越广泛,但传统上对桁架平面闸门多采用手工计算的方法,计算相对复杂。因而本文运用有限元技术,以挡洪闸的桁架平面闸门为例,采用静动力特性的分析方法进行分析,得到了该闸门在挡水工况、锁定工况和起吊工况下的静动力特性,为实际工程提供参考。

With the development of water conservancy in China,the application of large-span truss gates is more and more applied,but traditionally,manual calculation methods are used for truss gates,and the calculation is relatively complicated.Therefore,this paper uses the finite element technology,taking the truss gate as an example,and adopts the analysis method of static and dynamic characteristics to analyze the static and dynamic characteristics of the gate in the water retaining condition,the locking condition and the lifting condition,to provide reference for actual engineering.
