中文摘要：

提出了埋置框架的回传射线矩阵法，研究了方波脉冲轴向作用、水平作用和斜向作用下有缺陷埋置框架和无缺陷埋置框架的速度波．结果表明；横向速度波不能识别埋置框架的基桩缺陷，轴向速度波可以识别，而且基桩缺陷信号很强烈；脉冲水平作用不能识别基桩缺陷，轴向或斜向作用可以识别．

英文摘要：

There are no ready-made methods to calculate the transient response of pile foundations under a large number of structures in actual engineering, such as a frame structure embedded partially in soil under impact. The transient response of the frame structure embedded partially in soil may provide a theoretical basis for designing the marine platform, oil-line trestle and open type wharf under impact. The method of reverberation-ray matrix for frame structures embedded partially in soil is presented in this paper. The velocity wave of the perfect and defective frame structure embedded partially in soil is studied with square impulses in axial, horizontal or oblique directions. It is found that the defects of pile foundations of the frame structure embedded partially in soil can be identified via axial velocity under axial or oblique impulse.
