摘　　要：介绍了采用超声波法、敲击法以及钻孔渗水试验相辅验证的综合检测方法,定量评价钢管混凝土的钢管内壁与混凝土之间是否密贴或者脱粘的程度。有些部位的脱粘间隙很小,甚至钻孔后目测都很难发现,但采用渗水试验的结果表明了间隙的存在,验证了超声波检测的正确性。A solution composed of ultrasonic,tapping,hole-drilling and water penetration method for quantitative detecting the bond conditions between the steel and concrete was introduced.In some case,even the gap was too tiny for optic observation,the water penetration method can still detect it,verifying the correction of ultrasonic method.
