摘要
以常州市无辐式摩天轮轨道安装工程基准网的建立为实例,深入分析小范围高精度精密控制网的特点,研究了建立小范围高精度三维控制网的方法,重点针对同时涉及地面地下楼顶三种不同高度的控制网。以翔实的数据通过较系统的精度分析,提出对于在该情况下建立高精度控制网的有效方法,来保证整网的精度及可靠性,并结合实际总结了应用的作业经验。文中所有表格数据均取部分内容进行举例说明,并非完整实际工作数据。
This paper to changzhou no radial ferris wheel track installation reference network set up as an example, the thorough analysis of small range and high precision control characteristics, study the establishment of small range high precision 3 d control network method, focusing on the ground at the same time involved in the underground three different height control network. In view of detailed data through a system of precision analysis, put forward in this case to estab- lish high precision control network of effective measures, to ensure the accuracy and reliability of the network, and com- bined with the actual summarizes the application work experience.
