海上钢围堰建模方法的比较分析

摘要

本文以海上钢板桩围堰为研究对象,采用理正深基坑软件和Plaxis3D有限元分析软件分别建立数学模型,模拟施工中不同工况下,钢围堰的结构强度和稳定性的变化.通过分析比较两种模型的计算过程及结果,并结合工程实践提出了加强海上钢围堰整体结构稳定的具体措施.%The offshore cofferdam made of steel sheet piles is selected as a research object. And the mathematical models are built respectively by using Lizheng software of deep foundation pit of and Plaxis3D software of finite element analysis, which simulate the changes of structural strength and stability of steel cofferdam under different construction conditions. A comparative analysis is made for the calculation process of the above two models and the results. By referring to actual projects, the detailed measures are put forward, which will reinforce the overall structural stability of offshore steel cofferdam.
