摘要
介绍了根据《成都地震基准台地磁台异地新建项目台址勘选工作协议》要求,成都地磁台拟异地迁建新址的勘选过程及初选结果.勘选内容包括备选场地地磁总强度跨度测量、电磁环境背景噪声测量、地磁总强度密跨度测量、场地覆盖层土壤磁性测量等.勘选过程严格执行GB/T 19531.2-2004《地震台站观测环境技术要求第 2 部分:电磁观测》、DB/T9-2004《地震台站建设规范(地磁台站)》、DB/T 37-2010《地震台网设计技术要求—地磁观测网》等规范的相关要求,并对勘选结果进行初步分析.分析认为,勘选的备选台址成都市大邑县虎岗村符合地磁台站观测环境技术要求,可以建设地磁台站.
Abstract
This article mainly introduces the process and preliminary selection results of the proposed relocation of Chengdu Geomagnetic Station to a new site in accordance with the requirements of the"Agreement on Site Exploration and Selection for the New Project of Chengdu Earthquake Reference Station Geomagnetic Station in a Different Location".Selected candidate sites for geomagnetic total intensity span measurement,electromagnetic environment background noise measurement,geomagnetic total intensity dense span measurement,and soil magnetic measurement of the site cover layer.The survey and selection process shall strictly comply with the relevant requirements of the Technical Requirements for Seismic Station Observation Environment Part 2:Electromagnetic Observation GB/T 19531.2-2004,DB/T9-2004"Construction Specification for Seismic Stations"(geomagnetic stations),and"Technical Requirements for Seismic Network Design-Geomagnetic Observation Network DB/T 37-2010",and we conduct a preliminary analysis of the survey and selection results.It is believed that the selected alternative station site in Hugang Village,Dayi County,Chengdu City meets the technical requirements for the observation environment of geomagnetic stations and can be constructed.
