在桩基试验中,为了减小实测应变数据误差以及便于进行数据后续处理工作,我们往往需要将实测应变曲线进行趋势拟合。在前人提出的理论处理方法基础上,本文结合工程实例提出了几种对实测应变曲线进行拟合的方法,并对几种方法进行了比选,认为四次多项式拟合法是几种方法中较合理的一种拟合方法。

In our pile testing,in order to reduce the measured data error and convenience of data＇s post-treatment,we often need to trend fitting strain curves.On the basis of our predecessors＇ theoretical treatment method,in this paper,we combin a engineering example and give some methods fit pile＇s measured strain curves,we compare those methods and have a conclusion is that quartic polynomial fitting method is a more reasonable method.
