摘要
简要评述了现有强震记录仪器响应失真校正方法的优点和存在的不足。在文献[1]的基础上,提出了对强震记录进行仪器响应失真校正的权函数方法,并推导建立了相应的计算公式。通过设计真实地震动为已知的算例,对加速度摆和速度摆强震仪的未校正记录,和用不同方法获得的校正记录的精度(或误差)进行了对比分析。理论和算例分析表明,本文方法简单、实用,具有很高的计算精度且无稳定性问题。
After a short review of the state of the art of instrument response correction of strong motion accelerograms, a new method, called as 'weighting function method'is presented for the same purpose for strong motion data. In several numerical analysis, an assumed accelerogram was used as the input to the instrument base and calculated response of instrument was taken as the record of the instrument. The correction of the instrument record was carried out by several traditional approaches and the recommended one. A comparison among the actual input data, recorded response of instrument and the corrected records by traditional approaches and the recommended one showed that the weighting function method presented in this paper is much more precise and more efficient than the traditional ones.
