vertical displacement observation的意思|示意

This paper presents the consideration of establishing the bench marks, working bench marks, marks nets properly for the survey control net of vertical displacement in observation design.

本文介绍了在设计时，为设立完整而合理的垂直位移测控系统，对基准点、工作基点、标志和测控网布设的考虑。

System advantage is that it can amend mark point distortion, thus, accurate observation of vertical displacement can be got. Bimetal mark install veracity depends on quality of digging hole.

它的优点是能对温度所产生的标点变形进行修正，从而提高垂直位移观测精度，控制钻孔质量才能保证双金属标安装的准确性。

Itturns out that the accuracy increase is quite limited by using gravity observation to analyse vertical deformation, if the aim is only to determine point vertical displacement and its velocity.

结果表明，若仅是为了测定点的垂直位移的高程速率，增加重力测量数据后对形变分析的精度增益十分有限。
