中文摘要：
从工程应用角度详细介绍水工强震动加速度记录正确处理分析的方法与原理。主要介绍了震源的评估原理,强震动加速度记录预处理过程中单位换算、奇异点剔除、基线校正、滤波除噪等步骤的方法原理,后处理分析中一次、二次积分、谱分析原理。阐述了利用强震动加速度记录进行震害快速评估原理。文中以二滩拱坝强震监测台阵监测到的一次强震加速度记录的处理过程为例,以图表形式直接明了地强调指出了强震动加速度记录处理中容易发生错误的过程,并提出相应的处理方法。
英文摘要：
In this paper,the data processing methods and their theories for analyzing acceleration records obtained from strong motion observation arrays in hydraulic structures are introduced in detail.The data processing methods include seismic source assessment method,and some steps of data pretreatment process,such as data calibration,singular points eliminating,baseline correcting,de-noising by a filter,and first-order and second-order integral of acceleration and spectrum transform which belongs to data routine process.The calculation principles of the coefficient assessment of earthquake disaster are also studied.By taking a case study of strong motion data recorded at Ertan arch dam stations as an example,the paper points out the steps,which easily go wrong in data processing.And the corresponding countermeasures are proposed.
