摘要: 对比美标ASTM《D 1143M-07》(2013)与国标《建筑基桩检测技术规范》(JGJ106-2014)中关于单桩竖向抗压静载试验的适用范围、试验目的、测试方法、试验设备、试验步骤等5个方面,分析二者的不同,找出各自的特点,总结美标与国标之间试验过程的优缺点;对二者及国外其他通常采用的静载数据成果分析要求与承载力判定方法进行对比,找出中外单桩竖向抗压静载试验方法的数据处理及判定的异同点;对不同国家的工程项目进行实际验证,得到美标与国标的试验过程及结果的差异性,通过总结调整优化国外项目现场静载试验的具体要求,为外方技术人员认可我国桩基静载试验检测标准提供技术支持,同时也为我国桩基检测技术人员在国外进行基桩静载试验提供有价值的参考解决方案。

Abstract: This paper compares the five aspects of the static axial compressive loading test between the ASTM《D 1143M-07 Standard Test Methods for Deep Foundations under Static Axial Compressive Load》(2013) and the Chinese Standard “Technical Code for Testing of Piles for Building Foundations (JGJ106-2014); the applicable range, purpose of testing, test methods, test equipment and test procedures. The similarity and different aspects of two different test procedures and data process methods are studied. Throughout the comparative study, the Chinese test procedure was adopted by the foreign owner as well as the technical staff.

Key words: ASTM, JGJ106-2014, Static Axial Compressive Load Test, Experiment Method, Result Analysis
