摘　　要：直孔水电站坝基混凝土防渗墙质量检查采用了超声波无损检测和钻孔取芯相结合的方法,以超声波无损检测为主。检测中用到了超声波测强和超声波测混凝土内部缺陷两项技术,在不对墙体产生破坏的情况下可准确测出混凝土强度和混凝土内部缺陷的类型、位置、尺寸,效果良好,建议推广应用。The method of combining ultrasonic nondestructive testing with drilling core was used,taking the ultrasonic nondestructive testing as the main,to examine the quality of concrete diaphragm wall of the straight hole hydropower station dam foundation.Two techniques of using ultrasonic to test the intensity and internal defects in concrete were applied in the examination,the concrete intensity,the type,position and size of concrete internal defects may be detected correctly in the no damage on the wall-body case,therefore,to suggest popularization and application.
