摘　　要：新建盐卡泵站工程出水压力箱涵穿越长江荆江大堤,因地质条件复杂,历史上此堤段多次发生渗透变形破坏,是长江荆江大堤重要的险工险段之一。通过对穿堤建筑物的精心设计、施工,经检测资料分析和2020年长江高洪水位(超警戒)的实际运行考验,该穿堤建筑物工程设计与施工满足规范要求。The outlet pressure box culvert of the newly built Yanka Pumping Station crosses the Jingjiang Levee of the Yangtze River.Due to the complex geological conditions,seepage induced deformation and failure have occurred many times in this dangerous levee section.The design and construction of the levee-crossing structure are introduced.Analysis of the monitoring data and the practical operation of the levee under high flood level(exceeding the warning level)in 2020 show that the design and construction of the structure meet the specification requirements.
