摘要
按照《水库大坝安全评价导则》(SL 258—2017)和《水库大坝安全鉴定办法》(水建管〔2003〕271号)的要求,需要定期对大坝进行安全鉴定。文章以北京市玉渡山水库大坝为例,针对大坝运行过程中出现的缺陷和问题,对大坝混凝土强度、碳化深度、钢筋保护层厚度及钢筋锈蚀等进行了检测评价,提出了修补加固的建议,可为类似工程提供借鉴和参考。
According to the requirements of‘Guidelines on Dam Safty Evaluation’(SL 258—2017)and‘Safety Appraisal Method for Reservoir Dams’(Shui Jian Guan〔2003〕No.271).The safety appraisal should be carried out for dams regularly.Yudushan Reservoir Dam in Beijing is adopted as an example in the paper for testing and evaluating the concrete strength,carbonation depth,steel bar protection layer thickness and steel corrosion of the dam,etc.in view of the defects and problems in the operation of the dam.Repair and reinforcement suggestions are proposed,thereby providing reference for similar projects.
