【摘要】 本文提出了一种分析动测桩身缺陷波形特征的新理论,即子波效应学说。该学说将动测桩波形归为:主波+子波=实测时程曲线如果将主波从实测时程曲线中分离出来,子波与桩身缺陷之间的相关对应关系就能建立,从而桩身缺陷的形式与缺陷程度就能确定。文章根据子波效应学说对几种典型的变截面桩进行了求解分析,并指出了尚需进一步研究的问题。
【Abstract】 This paper puts forward a new theory for analysing the waveshape character by dynamic pile’s defect, namely,the theory of wavelet effect.The theory sums up the wave shapes of dynamic test pile: principal wave+wavelet=measured waveshape If the principal wave can be seperated from the measured waveshape,then the corresponding relation can be established between the wavelet and the characters of pile’s defect,and thus,quantitative analyses for the form and degree of pile’s defect can be realized.
