作为临时围护结构,水中钢板桩围堰的稳定性对工程施工安全的重要性不言而喻。对围堰进行变形监测研究,掌握变形状况,控制施工风险,不仅能够防范施工期间事故的发生,还能节约工程成本。通过分析某湖中大型通道项目施工中临时双排钢板桩围堰变形监测数据,研究围堰变形量和抽水过程中水位差的联系,经过拟合分析得出结论,可为类似水上工程设计和施工提供参考。
As a temporary envelope structure, the stability of steel sheet pile cofferdam is of importance to the construction safety. Deformation monitoring of the cofferdam, grasping the deformation, control of construction risk, not only to prevent accidents during construction, but also to reduce construction costs. By analyzing the deformation monitoring data of temporary double-row steel sheet pile cofferdam in the construction of large-scale channel project in a lake, the relationship between deformation of cofferdam and water level difference in pumping process is studied. After the conclusion of fitting analysis, Construction for reference.
