平陆运河工程施工控制网的建立

Establishment of construction control network for Pinglu Canal project

航道工程施工控制网是运河建设的重要课题。以平陆运河工程施工控制网的建立为例,根据枢纽建筑物施工放样的精度要求,确定平面控制网和高程控制网的等级。采用先进的测量仪器,快速完成控制网的外业数据采集,利用广西连续运行参考站(GXCORS)测量数据,集中统一处理全球导航卫星系统(GNSS)数据。高效率完成了施工控制网技术设计、外业数据采集、内业数据处理、精度分析、成果提供等全部生产过程。

The construction control network of waterway engineering is an important issue in canal construction.Taking the establishment of Pinglu Canal construction control network as an example,we determine levels of horizontal control network and elevation control network based on the precision requirements of the construction layout of hub buildings.We quickly complete the field data collection of the control network by advanced measuring instruments,and use the measurement data of Guangxi continuous operating reference station(GXCORS)to centrally and uniformly process GNSS data,so as to efficiently complete the production processes of construction control network technology design,field data collection,internal data processing,accuracy analysis,and achievement provision.
