埋置框架质量检测的探讨

Discussion on quality testing of frame structure embedded partially in soil

  • 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.

     

    Abstract: There are no ready-made methods to calculate the transient responseof pile foundations under a large number of structures in actualengineering, such as a frame structure embedded partially insoil under impact. The transient response of the framestructure embedded partially in soil may providea theoretical basis for designing the marine platform, oil-linetrestle and open type wharf under impact. The method of reverberation-raymatrix for frame structures embedded partially in soil is presented in thispaper. The velocity wave of the perfect and defective frame structure embeddedpartially in soil is studied with square impulses in axial, horizontal oroblique directions. It is found that the defects of pile foundations ofthe framestructure embedded partially in soil can be identified via axial velocityunder axial or oblique impulse.
