广西澄碧河水库混凝土防渗墙质量检测与评价

在病险水库与堤坝的除险加固勘测设计中,对于混凝土防渗墙的防渗作用以及质量检测与评价,存有一定的争议。鉴于此,以广西澄碧河水库混凝土防渗墙为例,采用钻探取芯以及孔内超声波和钻孔电视检测等方法，对混凝土防渗墙的质量与防渗效果进行了全面分析。结果表明：采用多种手段和方法进行比较分析，能得出更加符合实际的评价结果，进而采取有效的加固措施。

Quality check and evaluation of concrete cut-off wall of Chengbi River Reservoir

It is disputable for evaluation of seepage control and quality check of concrete cut-off wall in the survey and design of danger elimination and reinforcement of dangerous reservoirs and dikes.In view of this,in the case of Chengbi River Reservoir in Guangxi province,the quality and anti-seepage effect of concrete cut-off wall are analyzed comprehensively through the methods such as core drilling,ultrasonic detection in the borehole and acoustic borehole television detection.The result shows that actual res...
