浅水域钢管式无土围堰结构设计分析与监测研究

Structural design analysis and monitoring study of soilless cofferdam made of steel pipes in shallow water

以滁州大山风电场-古河110k V输电线路工程某塔位的钢管式无土围堰结构为研究背景,采取理论计算和多次力学重分析等手段,对该类围堰结构的选型与设计方法进行了系统的介绍,同时对该围堰结构的应力状态进行了有限元法分析和现场监测。分析结果表明,无土围堰结构的力学性能较好,设计合理。

The soilless cofferdam structure made of steel pipes of a tower of 110 k V transmission line project from Dashan wind farm to Guhe town in Chuzhou was taken as the research background. The theoretical calculation and repeated mechanical analysis method were adopted to carry out systematic introductions on system selection and design method of this kind of cofferdam structure. At the same time,finite element method analysis and field monitoring were conducted on the stress state of this cofferdam structure. The analysis results show that the soilless cofferdam structure has well mechanical properties and reasonable design.
