中文摘要:
      本文以山西禹门口灌区二级干渠渡槽加固改造工程为基础,针对渡槽存在的混凝土冻融剥蚀、碳化、钢筋锈蚀、止水损坏等缺陷病害问题,通过检测评估计算分析,提出了相应的修补加固技术方案和提高过流能力措施,工程经修复通水运行观察,相关病害处理效果明显,过流能力得到提高,达到安全运行和提高输水能力的目的。本文提出的修补加固方案可为类似工程提供借鉴。
英文摘要:
      Based on reinforcement and reconstruction project of the secondary canal in the Yumenkou Irriga-tion District of Shanxi, according to defects of concrete such as freeze-thaw, corrosion, carbonization, steel corrosion, water stopping material damaged and so on, through inspection and evaluation, correspond-ing repair and reinforcement schemes were proposed. After repair and operation observation, the treatment effects of engineering diseases are obvious,flow capacity has been improved,and the purpose of safe opera-tion and improving water conveyance capacity has been achieved. The repair and reinforcement scheme pro-posed in this paper can provide reference for similar projects.
