坝基混凝土腐蚀检测分析及腐蚀程度分级

Detection and Analysis on Concrete Corrosion Degree of Dam Foundation and Corrosion Degree Classification

随着地下水及空气等介质的长期侵蚀作用,坝基混凝土出现了不同程度的腐蚀缺陷或腐蚀损伤,坝基混凝土的工作性能直接影响大坝安全。针对坝基混凝土的工作环境特点,基于多种勘察方法,对坝基混凝土遭受腐蚀情况进行了检测分析,提出了坝基混凝土腐蚀程度检测分析方法及腐蚀程度分级评价体系。

Under the long-term erosion of groundwater,air and other media,the concrete of dam foundation has showed various degrees of corrosion defects or corrosion damage,and the safety of whole dam is directly affected by the working performance of dam foundation concrete.According to the characteristics of dam foundation concrete environment,different survey methods are used to detect the corrosion degree of dam foundation concrete,and the detection results are analyzed.Based on the results of detection and analyses,the dam foundation concrete corrosion detection and analysis methods and the corrosion degree classification and evaluation system are proposed.
