| 摘 要： | 基于现代无金属结构设计理念,首次提出了平原地区玄筋混凝土沉井式结构立体地磁记录室设计研究方案,该方案较传统设计在地磁记录室温差控制能力方面有大幅度的提高,可以为记录仪器提供稳定的温度工作环境;真正实现了"地磁观测",地下深层空间观测可以有效的屏蔽地表及外空间的大量干扰因素,地磁台站占地面积可明显减小,该地磁观测室观测资料的质量将会产生飞跃。

| Abstract: | Based on the design logos of modern nonmetallic structure, the design scheme oi open cais- son structure of basalt fiber reinforced concrete for the geomagnetic observation chamber on plain area is presented in first time in this paper. Compared with the traditional design, the new scheme can provides much better temperature control capability and a more stable tem- perature environment for the operation of recording instrument. This design can also archive the underground observation of geomagnetism and screened out a lot of interferences come from earth surface and outside space. The new scheme will reduce the area of geomagnetic observation station significantly and improve the data quality of the geomagnetic observation overly. |
