摘要
通过对管桩低应变法检测中桩顶拾振点位置的选取进行仿真研究,分析各种情况下应力波的传播过程,结合工程实例分析给出了管桩低应变法检测中桩顶三维效应的规避方式,以期促进低应变法的推广应用。
The study undertakes the simulation research on the selection for the location of the vibration pickup points of pile top during the low strain method inspection of pipe pile, analyzes the transmission process of the stress wave in all kinds of circumstances, and provides the avoiding ways of the pile top three-dimensional effect by combining with the analysis of actual engineering example, so as to enhance the application of the low strain method.
