预制方桩混凝土强度检测实例应用与分析

Real Test Case Application and Analysis of Concrete Strength of Prefabricate Square pile

通过对实际工程的几种检测方法推定数据的分析,研究了钢筋混凝土预制方桩的桩身强度检测的几种无损检测方法的误差差异,通过误差分析分别比较了回弹法、超声回弹综合法、钻芯法等几种方法按全国规程的推定强度及其误差分析结果。根据比较结论,提出了预制钢筋混凝土方桩的桩身抗压强度无损检测评定的应用建议。

Based on the analysis of test data understand of several test measures in real project, the author compared with the errors among different no damage detect approaches for the strength test of prefabricate square reinforced pile. Through the error analysis, compared with the strengths witch deduced according to the national code and error analyzed results of rebound, uhrasound- rebound and drill core approaches. The non destructive testing and assessment approach of press stress of prefabricate square reinforced pile was proposed based on the error analysis.
