深水基础锁扣钢管桩围堰施工过程仿真分析

Simulation Analysis on the Construction of Locked Steel Pipe Pile Cofferdam in Deep Foundation

针对深水基础锁扣钢管桩围堰施工安全问题,结合某斜拉桥主墩深水基础锁扣钢管桩围堰工程,采用midas Civil有限元程序建立钢围堰整体模型,仿真分析施工过程。计算分析得到锁扣钢管桩围堰受力规律、稳定性和变形情况。研究成果给出了确保深水基础锁扣钢管桩围堰施工安全的关键点和结构合理优化建议。

For the construction safety of the locked steel pipe pile cofferdam in deep foundation,combined with the locked steel pipe pile cofferdam project of the main pier of a cable-stayed bridge in deep foundation,the overall model of the cofferdam is established by midas Civil finite element program,and the construction process is simulation analyzed.The force law,stability and deformation of the cofferdam of the locked steel pipe pile are analyzed.The research results give key points and reasonable optimization suggestions to ensure the safety of the construction of the locked steel pipe pile cofferdam in deep foundation.
