摘要
大芦线东延工程采用对开式平面弧形闸门,作为一种新型闸门,具备水头低、跨度大、在水平面内运行、在国内应用较少等特点。以大芦线东延伸航道整治工程中的对开式平面弧形闸门作为研究对象,采用ANSYS软件构建了其有限元模型,对该闸门在危险工况下的静力学特性和模态特性进行了分析,并深入探讨了闸门下泄水流的流动特性。为了研究闸门在不同开度状态下的河道水流特性,采用Fluent对河道内的流场进行了分析,并将结果与物理模型试验中的流态数据进行了对比分析。此研究为对闸门的优化设计提供了依据,可为类似工程的对开式平面弧形闸门设计与结构分析提供借鉴。
The East Extension Project of the Dalu Line utilizes split-type plane arc gates,As a relatively new gate design,this kind of gate has the characteristics of low head,large span,operation in the horizontal plane,and limited application in China.In this study,the splittype planar arc gate in the East Extension Project of the Dalu Line was taken as the research object.The static and modal characteristics of the gate under dangerous conditions were analyzed by constructing finite element model using ANSYS software.Furthermore,the flow characteristics of the discharge flow under the gate were deeply discussed.In order to study the flow characteristics of the sluice gate under different opening conditions,the flow field in the river channel was analyzed by using Fluent,and the results were compared with the flow data in the physical model test.This study provides a basis for the optimal design of the gate,and can provide a reference for the design and structural analysis of the split-type planar arc gate of similar projects.
