A Method for Establishing and Verifying Multi-station Reference Networks Based on Free Station Setup and Traverse Transfer Combination
Addressing the shortcomings of common reference network establishment methods,this paper describes the common construction methods of reference network and their application,and puts forward a method of establishing a multi-station reference network based on the combination of free station setting and traverse transmission.Taking the protective monitoring project of Fuzhou Metro Line 6 as an exam-ple,the advantages and reliability of this method are verified.The results show that the mean coordinate error is less than 2mm,which can meet the specification requirements and provide valuable reference for the construction of urban subway and other underground engineering projects.
