基于实际工程的典型基桩时域曲线判别

Discrimination of Typical Foundation Pile Time-domain Curve Based on Actual Engineering

声波反射法是目前广泛应用的基桩完整性检测的方法,基桩时域曲线是判定桩身完整性的主要依据。结合实体工程,介绍了声波反射法中时域曲线特征参数的获取,分析了离析桩、缩颈桩、桩底沉渣等典型基桩的时域曲线,为工程实际应用提供参考。

Acoustic reflection method is wildly used in integrity testing of foundation pile. Pile timedomain curve is the main foundations to judge the integrityof pile shaft. Combined with entitative construction,obtaining temporal characteristics curves parameters in sound wave reflection method is introduced,time- domain curves of typical pile like segregation of pile,necking pile,pile bottom sediment and so on are analyzed to provide a reference for practical engineering application.
