高应变动力试桩技术及应用

The Technique and Application of High Strain Dynamic's Detecting Piles

对高应变单桩承载力和高应变法检测桩质量的计算原理进行论述和公式的推导 ,并举例说明对高应变检测桩承载力和检测桩身质量的误差可以满足《规范》要求 ,提出只要认真对待检测的每一个环节 ,提高精确度是可能的 。

This essay not only argues the calculation principles of determining apile bearing capacity and the masstesting with high strain method,but also derivating the relative formulas.It illustrates that the error meets the need of specification and that it's possible to improve the accuracy provided we can treat every one of steps carefully.In the end,it give us some occuring problems.
