摘要
结合工程现场实例,简要论述了低应变反射波检测方法的原理和工程中常见的浅部缺陷桩,并详细分析了实际检测工作中典型浅部缺陷的低应变反射波形曲线.根据实测波形资料,总结了检测工作中常见的各种浅部缺陷桩的波形特征和技术要点,为判别基桩缺陷性质提供借鉴.通过对基桩浅部异常波形曲线的详细分析,避免实际检测工作中的错判或漏判.
Abstract
Combined with the examples of the engineering site,the principle of the low strain reflection wave de-tection method and the common pile with shallow defects in the project are briefly discussed,and the low strain re-flection waveform curve of typical shallow defects during actual detection is analyzed in detail.Based on the mea-sured waveform data,the waveform characteristics and technical points of various common piles with shallow de-fects during detection are summarized,which provides reference for distinguishing the defect properties of founda-tion piles.The shallow abnormal waveform curve of foundation piles is analyzed in detain,so as to avoid erroneous judgement or missed judgement during actual detection.
