近年来,桩基础无破损检测方法(以下简称桩基动测)在我国有较迅速的发展。锤击法是人们常用的检测桩基质量的简便易行可靠的一种方法。但人们在实践上往往会遇到一些难以按评判原则进行分析解释的波形,除了测试技术或仪器的原因外,随机性干扰波及缺陷界面的非平整性使入射波在传播过程中在缺陷界面上发生多次反射,能量耗散较大,当反射波到
In recent years, the detection method of pile foundation without damage (hereinafter referred to as pile foundation motion measurement) has developed rapidly in China. Hammering method is a simple, easy and reliable way for people to detect the quality of pile foundation. However, in practice, people often encounter waveforms that are difficult to analyze and interpret according to the principle of evaluation. In addition to the causes of testing techniques or instruments, the non-planarity of the random interference interference flaw interface causes the incident wave to propagate on the defect interface. Multiple reflections occur, the energy dissipation is greater when the reflected wave arrives
