［摘要］以滁州大山風(fēng)電場-古河110kV輸電線路工程某塔位的鋼管式無土圍堰結(jié)構(gòu)為研究背景，采取理論計算和多次力學(xué)重分析等手段，對該類圍堰結(jié)構(gòu)的選型與設(shè)計方法進行了系統(tǒng)的介紹，同時對該圍堰結(jié)構(gòu)的應(yīng)力狀態(tài)進行了有限元法分析和現(xiàn)場監(jiān)測。分析結(jié)果表明，無土圍堰結(jié)構(gòu)的力學(xué)性能較好，設(shè)計合理。

Abstract:The soilless cofferdam structure made of steel pipes of a tower of 110kV 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.
Keywords:soilless cofferdam; shallow water; stability; construction monitoring
