一种组合式钢围堰的设计与分析

Design and Analysis of a Combined Steel Cofferdam

南水北调工程是我国的重大民生工程,其渠坡在不断水情况下的维修及保养是目前急需解决的重大难题。本文以所需施工要求和现有水文环境为出发点,经过计算分析围堰系统的整体受力、系统稳定性及对边坡的压力等数据,初步确定围堰各部件的尺寸结构,使用CATIA建立的围堰三维模型并导入ANSYS软件进行静力学和瞬态动力学分析。通过仿真结果分析围堰变形情况,以保证设计安全并为以后的优化提供依据。

The South-to-North Water Transfer Project is a major livelihood project in China. The maintenance and maintenance of the canal slope under continuous water conditions is a major problem to be solved urgently. Based on the required construction requirements and the existing hydrological environment, the size and structure of each component of the cofferdam are preliminarily determined by calculating and analyzing the data of the overall force, system stability and slope pressure of the cofferdam system. The three-dimensional model of the cofferdam established by CATIA is introduced into ANSYS software for static and transient dynamic analysis. Analysis. The deformation of cofferdam is analyzed by simulation results to ensure design safety and provide basis for future optimization.
