摘要
针对目前利用低应变时域分析和频域分析方法无法准确识别管桩桩身存在的细小裂缝的技术问题,结合理论分析、模型桩对比试验、实例验证的方法,通过时频分析法与小波分析法的对比,探究小波分析法识别管桩细小裂缝的可行性与可靠性。
The technical problem by using the time domain analysis and frequency domain analysis of the low strain method is that it can not accurately identify the micro-cracks in pipe piles. Based on the theoretical analysis, comparison tests on the model piles and verified method, the feasibility and reliability of the wavelet analysis identifying micro-cracks in pipe piles are studied by comparing of the time-frequency analysis and the wavelet analysis.
