基于GTS的黏土中缩颈桩检测研究

Research on Detection of Necking Piles in Clay Based on GTS

利用GTS有限元分析软件,对黏土中的缩颈缺陷桩进行数值模拟,得到不同阻尼系数及在不同缺陷位置下的反射波曲线。对结果对比分析,总结出振幅比随缩颈桩缺陷变化的规律,以及缩颈桩的缺陷程度与波振幅比之间的关系,对于工程桩的检测具有重要的指导意义。

According to the software of GTS finite element analysis,the article obtains the reflected wave curves at different damping and different defective positions by the numerical simulation for necking defect piles in clay. Through the comparative analysis of the results,it summarizes the law of the variation of the amplitude ratio as the necking defect pile changes,and also the relationship between the defect extent and amplitude ratio of the necking pile,which has the great significance for the detection of engineering piles.
