摘要
利用反射波法检测高桩码头基桩完整性时,由于基桩存在上部结构,反射波波形会含有干扰信息,变得十分复杂。文章研究了小波分析在高桩码头基桩完整性检测中的应用,利用小波分析消除干扰信号,以减弱梁板等上部结构对基桩检测信号的影响,最后通过具体的工程实例进行了应用验证。
When using reflected wave method to detect the pile integrity of high-piled wharf,due to the existence of superstructure,reflected waveform usually includes interference information and becomes very complicated.In this paper,the wavelet analysis in high-piled wharf pile integrity testing was studied to eliminate the interference signal and weaken the effect of superstructure on the pile testing signal.Finally,its practical application was proved by taking an engineering project as an example.
