摘要
根据混凝土面板坝施工的特点并综合考虑某引水工程坝址处的自然环境等因素,分别运用回弹仪、裂缝测宽仪、超声波探伤仪与地质雷达对面板混凝土强度、面板裂缝宽度、裂缝深度及堆石与面板间是否存在脱空进行了检测.根据检测结果对大坝面板混凝土表面产生裂缝的原因进行了分析,并提出了混凝土面板坝表面裂缝在不同情况下的处理方法.
According to the characteristics of the concrete panel dam construction and natural environment of someone reservoir project.The concrete panel strengthen,the width of surface crack,the depth of surface crack and the cavity pocket between panel and rock filling were detected through rebound tester,width gauge,ultrasonic flaw detection equipment and geological radar.The cause of crack in dam panel was analyzed on the basis of the detection results.According to the different types crack,the processing methods were presented in treating the dam panel.
