摘要
利用兰州台阵勘址观测中方的资料 ,对勘址测点的信号与噪声的相关值进行了计算与分析 ,结果得出检测PG与P震相的最佳内外环半径分别为 380m和 15 0 0m .根据台阵内外环半径的计算结果 ,以及内外环子台不要按放射状排列的要求 ,从勘址测点中选出了满足背景噪声水平要求的 9个子台作为初选台阵 ,并对初选台阵进行了评估 .结果表明 。
By using the waveform data recorded during the site survey of Lanzhou Seismic Array, the author calculated and analyzed the correlation of signal and noise between element pairs and find the ideal radius of the two concentric circle for Lanzhou Seismic Array are 380m and 1 500m respectively. According to the radius limit and other requirements, nine element sites were chosen to be made of an seismic array, then the detection and location ability of the array were estimated to be excellent.
