deformation observation point

基本解釋

This article introduces resection locating temporary work datum point by distances and angles in control network for deformation observation.
介紹了應用全站儀測邊、測角後交定點的基本原理和佈設變形監(jiān)測網(wǎng)中臨時工作基點方法。
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.
結(jié)果表明，若僅是爲了測定點的垂直位移的高程速率，增加重力測量數(shù)據(jù)後對形變分析的精度增益十分有限。
