摘要
介绍了云南数字遥测台网的基本情况,阐述了地动噪声有效值和功率谱的计算方法。对选取的资料进行预处理后,计算分析了云南数字遥测台网全部子台的地动噪声水平,按地动噪声水平对子台进行了分类。指出了地动噪声分析对台网建设的作用。
The basic situation of Yunnan Digital Remote Network has been introduced. The method calculating the effective values and power spectra of the ground motion noise has been described in this paper. After the preprocessing of the selected data, we calculate and analyze the noise level of ground motion at every substation of Yunnan Digital Remote Network, according to which the substations are classified. The effect of ground motion noise on the network construction is analyzed.
