钢-混凝土组合结构的超声波检测方法

研究了钢－混凝土组合结构中该二者间的胶结质量以及核心混凝土密实性的超声波检测方法，工程实践表明，采用常规的超声仪换能器布置方式对钢－混凝土组合结构胶结质量进行检测是可行，有效的，在该二者胶结牢固的场合下，超声波束能穿过外围钢板并在混凝土中传播，从而可以检测核心混凝土内部的密实性。

Ultrasonic Evaluation on the Steel-Concrete Combination Structure

An ultrasonic test method was presented to evaluate the adhesive quality of steel concrete combination structure and the density of the core concrete. It was proved to be practical and feasible by using an ordinary ultrasonic method in field test. The ultrasonic wave can penetrate the steel plate around and propagate through the concrete, which can be used to estimate the density of the core concrete.
