高应变动力试桩的误差分析

Errors Analysis of High-strain Dynamic Pile Testing

相对静载试验而言,高应变动力试桩的误差来源要丰富得多。本文较系统地对这些误差进行总结,提出了浅层次、中层次和高层次的误差的概念,并通过工程实践分析说明。对如何减小误差、更好地应用和发展高应变动力试桩技术提出建议。

Compared to static load testing, the testing errors source of high strain dynamic testing is more ahundant, In this paper, testing errors of high strain dynamic testing was systematically introduced. The concept of three levels of erros existing in the process of high strain dynamic testing was put forward and demonstrated by the case. Some suggestions were given for reducing testing errors and promoting the application and development of high strain dynamic testing technique.
