摘　　要：应用水下电视探测技术结合常规检测手段,通过现场试验,对多项疑难复杂的水下工程桩身结构完整性进行了准确合理的判定,对缺陷的程度、位置,及造成缺陷的原因提供了可靠的分析依据,该项技术配合常规检测方法,对仲裁有争议的砼管桩、砼空心方桩的桩身缺陷方面具有重要的实用价值。Underwater television detecting technique, in conjunction with conventional testing methods, has been used to make correct and reasonable judgment of the structural integrity of the underwater section of working piles in difficult and intricate conditions for a number of projects and has provided reliable basis for the analysis of the degree and location of defects and the causes of the defects. In conjunction with the conventional testing methods, the underwater television detecting technique can be of significant useful value for arbitrating disputable defects in pile shaft of reinforced concrete pipe piles and reinforced concrete hollow square piles.
