超声波对混凝土强度的无损检测

Ultrasonic Nondestructive Testing in Concrete's Intensity

传统的超声波测试和诊断主要检测金属内部的缺陷和其它领域混凝土的强度,该文主要介绍了混凝土超声无损检测技术的原理及应用,并结合实际开发了一套基于超声波的智能无损检测装置,它专门用于火灾后的混凝土强度测试。经过对两种不同高温下的混凝土试验构件进行测试,结果表明,电路整体的设计完全达到了要求。

The traditional ultrasonic test ＆ diagnosis device is mainly aimed at diagnosing the inner defects of metal and is an intensity test of field concrete. A new intelligent uhrasonie diagnosis device specially applied to the firedamaged concrete intensity test is introduced in this paper. This intelligent diagnosis device can capture the first wave automatically and it reduces the manual errors. The hardware and software design of the intelligent diagnosis device is introduced meanuhile the specific design method is given. With the actual test of the concrete intensity after fire,it is proved that this device is more precise than the traditional ultrasonic device.
