摘要
超声测强法不能普遍应用于大直径混凝土灌注桩的主要困难是因为仪器零读数和桩体内部声测管间距难以准确确定,本文根据工程实践经验,提出了解决超声法测定大直径混凝土灌注桩桩体混凝土强度的方法,具有一定的实用价值。
The main reason that the ultrasonic strength testing method can't be widely used in detecting great
cast-in-situ concrete piles is difficult to determine precisely the initial readings of the measuring instrument
and the distaces of measuring tubes. This paper gives the solution for using ultrasonic method to detect
conerete stoength of cast-in-situ concrete piles. It will be great value in practice.
