摘要
阐述了基桩倾斜无损检测基本原理——惠更斯-菲涅尔原理。通过在桩侧面实施地震排列装置检测试验,证实了桩倾斜度越大,桩侧效应越强。在倾斜基桩中埋设三分量检波器检测结果说明,基桩倾斜时,桩侧界面响应主要以转换后沿界面方向的纵波与垂直于桩侧面的横波为主。
In this paper, the authors deal with the basic principle for nondestructive test of the pile inclination. Based on the implementation of the seismic alignment on the top of the pile, it is found that the larger the inclination degree of the pile, the bigger its side effect, and that, when the pile is inclined, the main response on the side of the pile is the primary wave and the transverse wave. An experiment on the pile inclination with the help of a three-component detector has proved these conclusions.
