Study on the Monitoring of Vertical Central Deformation and Turn Round of Sichuan TV Tower

介绍了利用GPS静态观测事后处理分析的方法监测四川广播电视塔中心线的垂线度及塔身扭转的有关问题。内容包括基准网的建立与稳定性分析 ;塔心及塔轴线基准数据的确定 ;塔中心线的垂直度及塔身扭转的监测方法及数据处理。对实测数据的分析研究表明 ,采用GPS监测方法取得的结果是令人满意的。

This paper mainly discusses the issues of monitoring the verticalness central deformation and the turning round of Sichuan TV tower by post-processing static observation of GPS. It covers the range of reference network construction and reliability analysis, datum determine of TV tower center and its axel line, the monitoring and data processing method of TV tower's vertical central line and its turning round of the axel line. The analysis and study of monitoring data shows that excellent result has been obtained by GPS. The article is of great value to people dealing with engineering surveying of TV tower or similar high objects under construction.
