大直径混凝土灌注桩桩身质量检测方法探究

Research on Quality Inspection Method of Large Diameter Concrete Cast in Place Pile

为了保证大直径混凝土灌注桩的桩身完整性,一种有效的检测方法是必要的。传统的低应变检测方法在此类桩基完整性检测中的应用结果和抽芯结果有显著的差异,因此对大直径混凝土灌注桩的桩身完整性检测,需要结合多种检测方法才能对其完整性进行判别。

In order to ensure the integrity of large diameter cast-in-place concrete pile,an effective detection method is necessary.Based on the practical engineering application examples,the application results of traditional low strain detection methods in this kind of pile integrity detection and core pulling results are significantly different.Therefore,for the pile integrity detection of large-diameter cast-in-place concrete pile,we need to combine a variety of detection methods to judge its integrity.
