地震动基线漂移校正方法的比较研究

A Comparative Study of Baseline Drift Correction Methods on Ground Motion

为了解决由地震加速度记录积分得到的地震动位移时程曲线出现的严重零线漂移现象,本文简要总结了三种校正地震动基线漂移的方法,即Jianbo li法、Boyce法和Trujillo法,并通过算例比较各种方法的校正效果,对比三种方法的校正效果,提出一种较简捷的方法应用在工程中。

In order to solve the serious zero-line drift phenomenon which appears in the process of the earthquake acceleration integral to obtain the time-history curve of the ground motion displacement.In this paper,three methods of correcting the baseline drift of ground motion are briefly summarized,namely the Jianbo li method,the Boyce method and the Trujillo method.The correction effects of various methods are compared with the calculation examples.A relatively simple method is proposed to be applied in engineering.
