适应衬砌渠道修复的组合式钢浮箱围堰方案的稳定性计算

Stability Calculation of Combined Steel Pontoon Cofferdam Scheme Suitable for Lining Channel Repair

调水工程的衬砌渠道在运行过程中,难免受到损坏而需要进行修复作业。面对大范围的渠道衬砌板修复,提供安全、可靠的干地修复环境是修复作业的前提。论文总结归纳了衬砌渠道的修复原则,并对组合式分段钢浮箱围堰导流方案的稳定性进行校核。结果表明,多个钢浮箱组合成的钢围堰的稳定性满足要求,能够适应衬砌渠道养护作业。

The lining channel of water transfer project is inevitably damaged and repaired during operation.Facing a wide range of channel lining board repairs,providing a safe and reliable dry ground repair environment is a prerequisite for repair operations.This article summarizes the repair principles of lining canals,and checks the stability of the combined segmented steel pontoon cofferdam diversion scheme.The results show that the stability of the steel cofferdam formed by combining multiple steel pontoons meets the requirements and can adapt to the maintenance operations of lining canals.
