摘要
基桩桩身完整性是工程桩施工质量综合判定的关键指标,该文基于工程应用实例对比分析与综合评价4种不同基桩完整性检测方法(低应变法、声波透射法、钻芯法和高应变法)在工程基桩检测中的优劣势。分析与评价结果表明,不同检测方法各有优势,亦存在不同的局限性,在实际工程应用中应根据不同基桩的特点、要求和试验条件科学合理选择相应的桩身完整性检测方法。
The integrity of foundation pile is the key index for comprehensive judgment of engineering pile construction quality.Based on the comparative analysis and comprehensive evaluation of four different pile integrity testing methods(low strain method,acoustic transmission method,core drilling method and high strain method)based on engineering application examples,this paper makes a comparative analysis and comprehensive evaluation of the advantages and disadvantages of four different pile integrity testing methods(low strain method,acoustic transmission method,core drilling method and high strain method).The results of analysis and evaluation show that different testing methods have their own advantages and limitations,and the corresponding pile integrity testing methods should be selected scientifically and reasonably according to the characteristics,requirements and test conditions of different piles in practical engineering application.
