标准简介

适用范围：

This standard specifies general requirements for the measurement and analysis system of testing instruments, covering the composition, configurations, working conditions, typical performance, test methods, and inspection rules for judging the integrity of deep foundations and the determination of defect severity and defect locations of deep foundations. A deep foundation is a foundation that is installed to a significant depth greater than 3 meters to handle a specific load. However, the depth… read more depends on the engineering construction and geological conditions. A low-strain testing instrument utilizes low-energy (a few newtons to several hundred newtons) transient-state or steady-state excitation to induce low-amplitude vibration of the pile under elastic deformation. It utilizes wave theory to determine pile defects. The standard specifications include classification, measurement system, analysis system, and safety requirements. read less
