| 摘 要： | 高应变法检测是基桩检测技术的一种重要手段,但是该方法检测承载力存在误差,因此受到许多争议。本文以广东惠州地区两项工程的检测实践为例,分别采用前后两组不同拟合参数,对检测数据进行了承载力拟合计算,分别得出了前后两种不同的计算结果。并通过动、静两种方法的对比检测,分析了高应变法检测承载力误差产生的主要原因,粗略探讨了对高应变法检测的一些认识。

| Abstract: | High strain dynamic testing is an important means in the foundation pile testing technology. Currently there exist a lot of disputes due to its deviation in bearing capacity tests. In this paper, I choose two engineering testing examples in Huizhou city area of Guangdong province. The testing data are fitting calculation of bearing capacity by using two groups before and after different fitting parameters, and the calculation results are obtained two different before and after respectively. I analyze the main causes of deviation produced in high strain dynamic testing the bearing capacity through dynamic testing and static testing contrast analysis method, and discuss some ideas of high strain dynamic testing. |
