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例,针对其存在的混凝土冻融剥蚀、严重碳化、钢筋锈蚀、裂缝等老化病害问题,在检测评估的基础上提出了相应的修补加固技术方案。工程修复后经过通水运行观察,相关病害得到了有效处理,渗漏问题得到了彻底解决,渡槽运行水位明显下降、流速增大,过流能力有了明显提升,工程处理取得了良好的效果。In the paper,Shanxi Yumenkou Irrigation Area Stage II Canal Aqueduct Reinforcement and Transformation Project is adopted as an example. Corresponding repair and reinforcement technical plan is proposed on the basis of testing evaluation aiming at aging and disease problems thereof such as concrete freeze-thaw erosion,serious carbonation,steel bar rust,crack,etc. Water penetration operation observation is implemented after project repair. Related defects are effectively handled. Seepage problem is completely solved. Aqueduct operation water level is lowered prominently,flow velocity is increased,the overflow ability is obviously improved,and project handling is fruitful.
