Abstract: As poor quality of rolled compacted concrete, seepage, calcium blooding and high uplift pressure, Shuidong dam was evaluated as defeated dam in 2001. During 2002~2003, combination of anti-seepage curtain and upstream crack treatment was implemented in dam rehabilitation. Based on the operation in the last decade, the conclusion was gotten that the rehabilitation was of good effect and worthy reference.

摘要： 水东大坝由于部分碾压混凝土质量较差、坝体渗漏和析钙以及坝体扬压力偏高等问题，2001年被评定为病坝。2002～2003年首次定检采用构建坝体防渗帷幕和上游面裂缝处理相结合的方案对大坝进行防渗补强加固。对近十年的运行情况进行综合分析评价认为，水东大坝补强加固效果显著，其处理技术方案对类似工程具有良好的借鉴意义。
