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 ,同时提出存在的一些问题 The calculation principle of high strain single piles bearing capacity and high strain method testing pile quality are discussed and the formula is deduced. An example is given to illustrate that the error of the bearing capacity of high strain testing piles and the testing pile mass can meet the requirements of " It is possible to take every aspect of the test seriously and to improve the accuracy. At the same time, some problems
