以宝坻新台为例，介绍了管形构件结构地磁相对记录室的方案设计和施工要点，分析采用玻璃钢管形构件建设的地磁相对记录室的实际效果，得出玻璃钢管形构件结构方案是值得推广的一种地磁相对记录室结构新方案的结论。

As an example, introduce the tubular member geomagnetic variation recording room 's design and construction of new Baodi seismic station.Analysis the geomagnetic variation recording room’s actual results made of glass steel material tubular member. Point out that the geomagnetic variation recording room chamber structure scheme based on glass steel tubular member is a good scheme.
