摘要
通过对连云港地震台台基背景噪声进行计算和分析,得出该台台基背景噪声属于Ⅰ类噪声水平。分析该台6—7月观测数据,得出日夜噪声差值约3 dB。分析发现,该台人为干扰为基础建设的工程车干扰、景区人员聚集和车辆干扰;自然环境干扰主要来自大风干扰。
The seismic background noise of Lianyungang Seismic Station belongs to classⅠnoise level by calculation and analysis,and the noise difference between day and night is about 3 dB by analyzing the waveform data of Lianyungang Seismic Station from June to July.The man-made interference of the seismic background noise of Lianyungang Seismic Station is the interference of engineering vehicle for infrastructure,personnel gathering and the vehicle in the scenic spot,and the natural environment interference is mainly caused by strong wind.
