强震动记录数据质量初探
Preliminary study on data quality in strong motion records
摘要
Abstract
Strong motion records are of great significance for the earthquake disaster prevention and earthquake emergency in our country. Results and suggestions are as follows: (1 Preliminary definition of related concepts on strong motion records quality is presented, including the quality of strong motion records and recording process; (2 Such abnormal phenomena as incomplete waveform, low SNR, singular waveform (non symmetry, baseline offset and obvious acceleration spikes etc.) in strong motion records are summarized; (3 Eight measures are put forward to improving the quality of strong motion records in order to ensure records integrity, consistency, accuracy and timeliness.关键词
