文章介绍了我国南沙岛礁地磁台的现状和需求,建站的意义、自然本底、现有条件保障;场址勘选、建设方案、材料选择与检测、磁场梯度监控、验收检查、建站的困难及相关经验总结。通过竣工磁场梯度检测,满足专项工程技术规程海岛礁数字地磁台站建设规范的技术要求,说明方法切实有效,可为其他海岛礁地磁台站的新建、改造提供参考。
This study introduced the current situation and requirements of the Nansha Islands and Reefs Geomagnetic Observatory in China, including the significance of station construction, the natural background, existing conditions guarantee, site survey and selection, the construction plan, the choice and testing of materials, inspection and acceptance, and summary of difficulties in station construction and relevant experience. By completing the magnetic field gradient detection, it meets the technical requirements of the special engineering technical regulations for the construction of digital geomagnetic stations on islands, demonstrating the effectiveness of the method and providing a reference for the construction and renovation of other island and reef geomagnetic stations.
