| 摘 要： | 利用动测桩中的桩底反射信号研究了应力波在桩体和土体中的衰减情况。结果表明，应力波在桩体中的衰减比在土中小的多，在考虑了桩周土与反射系数的关系后，尝试给出应用桩底反射信号与桩头人射信号振幅之比判定单桩承载力相对大小的基本理论和初步研究结果。

| Abstract: | Wave attenuation has been studied in pile body and pile-earth system by dynamically measuring the renection signals from the bottom with the reflective wave method in this paper. The result shows that wave attenuation of pile in air is much less than in earth. Considering the result and relation of earth around pile and reflective parameter, an attempt has been made to determine relative load-bearing capacity by means of amplitude ratio of reflectitre wave method. |
