摘要
介绍利用超声反射法原理检测砼空芯方桩壁厚的两种方法,即测声速法和直接测厚法(直接显示厚度),并简要介绍超声检测的电路原理和实验结果。
Two ways to measure the wall thickness of hollow concrete cubical pile based on the idea of ultra-sonie echo method are introduced including acoustic velocity measuring method and thickness measuring methoc (displaying thickness directly). Circuit diagram and experimental results are also given.
