摘　　要：某湖与河渠相连,因河渠水环境较差导致该湖生态环境较差,形成黑臭水并出现蚊虫多、鱼类死亡、植物死亡等现象。拟建导流箱涵将湖区和河渠分离,确保湖区水体环境质量。文章以箱涵为研究对象,探讨有水运行期和无水运行期2种工况下的结构受力分析。同时,采用有限元软件ANSYS建立了箱涵结构模型,对箱涵结构的受力分析进行了研究,结果表明箱涵结构受力的大小与箱涵内有无水存在差异。A certain lake is connected to a river channel.Due to the poor water environment of the river channel,the ecological environment of the lake is poor,resulting in the formation of black and odorous water and the occurrence of many mosquitoes,fish death,plant death,and other phenomena.This study proposes a diversion box culvert to separate the lake area from the river channel,ensuring the quality of the water environment in the lake area.The article takes box culverts as the research object and explores the structural stress analysis under two operating conditions:water operation period and no water operation period.At the same time,a box culvert structure model was established using finite element software ANSYS,and the stress analysis of the box culvert structure was studied.The results showed that there was a difference in the magnitude of the stress on the box culvert structure compared to the presence of water in the box culvert.
