低应变动测信号采集和信号分析问题的探讨

Discussion on the problems in low strain signal accumulation and analysis

根据应力波的动力学和运动特征,结合施工工艺和大量的检测结果,对桩身浅部的断裂、裂缝、孔洞、夹泥、桩头疏松等异常信号进行判断,并对信号采集及信号分析常遇的问题进行了研究和讨论,以期提高检测结果的准确性。

According to dynamics and movement characters of stress wave and combined with the construction technology and quantity detecting effects, it makes judgment to abnormal signal of the rupture of pile shallow section, crack, cavity, silt laden, the loose of pile end, and gets the research and discussion to the common problems in signal accumulation and analysis, to increase the accuracy of detecting effect.
