摘要
城市轨道交通工程所有的测量工作均是以控制网的布设为基础的,其点位布设的合理与否将直接对工程施工进度及质量产生影响。首级平面控制网作为控制网布设首要性工作,在各项工作中显得尤其重要。本文针对城市轨道交通首级平面控制网的特点,结合石家庄市轨道交通2号线一期工程首级平面控制网的布设实践,介绍了城市轨道交通工程首级平面控制网布设过程中所遵循的原则以及数据外业采集、处理等过程中的技术要求及精度指标,工程实践结果显示该方法不但可以大大提高轨道交通工程控制网布设的作业效率及测量结果的精度,同时因其网络时效性的应用,还可以在很大程度上降低作业人员的劳动强度及作业成本,应用前景非常广阔。
The layout of control network is the foundation of all measurement work in urban rail transit project.As the primary work of control network layout,the frame control network is particularly important in all kinds of work.According to the characteristics of the frame control network in urban rail transit,combined with the layout practice of Shijiazhuang city rail transit line 2,this paper introduces the layout and measurement of the frame control network in urban rail transit project.According to the application in practical project,the results show that this method can greatly improve the operational efficiency of the control network layout in rail transit project.At the same time,because of its application,it can greatly reduce the labor intensity of the operators,and it has a broad application prospect.
