摘　　要：从台阵波数响应特性、子台选址与测试、场地背景噪声分析和记录信号评价等方面 ,综合对上海地震台阵进行设计 ,确定了台阵子台的布局点位。本文还介绍了规则台阵与不规则台阵中的几种不同子台布局的台阵波数响应图 ,并由此得出 ,采用不规则的子台布局同样可得到性能较好的地震台阵 ;台阵的子台越多 。Through the considerations of wave-number response characteristic of array,the site-selection and testing of substations,the noise analysis of field background and estimate of recording signals,in this paper we introduce the design of Shanghai Seismic Array,determining the locations of the substation sites for the array.Also,we present wave-number response characteristic of arrays with different deployments,such as the regular arrays and irregular arrays.And it comes to the conclusions that the irregular deployments may obtain the better feature of seismic array the same as the regular ones,and the more the number of substations,the more sharp the peak of the response figure.
