旧桥基础桩弹性波CT成像的实验研究

摘要

The paper undertakes the elastic wave CT method to undertake the CT image on the foundation pile on old bridges or operation,indicates the built pile length,pile quality and quality of bearing stratum of the pile bottom of the foundation pile,proves the effectiveness of the method by the inspection images of the foundation piles and model pile of the various foundation piles,and points out the defects o the method.%采用弹性波CT法,对旧桥或营运中的基础桩进行CT成像,勘查已落成基础桩的桩长、桩身质量及桩底持力层质量等情况,并通过多根埋设已知桩长、桩身质量的旧桥基础桩及模型桩检测成像实例,验证了该方法的有效性,最后提出了该方法的不足之处.
