临安地震台阵勘址与场地条件分析

Site selection survey and field condition analysis of Lin’an Seismic Array in Zhejiang Province

介绍浙江临安地震台阵勘址工作,包括各子台位置关系、区域自然地理与气候条件,着重分析区域大地构造、地质发展史以及测试点位的基岩性质等地质条件,结合岩土工程勘察资料,分析认为选定区域适合地震台阵建设,简述台阵供电与通讯初步设计方案,为后期地震台阵建设提出指导意见。

This paper describes the site selection survey of the Lin’an Seismic Array in Zhejiang Province,including the positional relationship of the sub-stations,regional natural geography and climate conditions.Our study specially focused on the analysis of the geological conditions such as the regional tectonic structure,the history of geological development,and the nature of the bedrock of the test site.Combined with the geotechnical engineering survey data,it is considered that the selected area is suitable for the construction of the seismic array.This paper describes the preliminary design scheme for the power supply and communication of the array and puts forward the guiding opinions for the following seismic array construction.
