基于自由设站与导线传递结合的多测站基准网建网与复核方法

A Method for Establishing and Verifying Multi-station Reference Networks Based on Free Station Setup and Traverse Transfer Combination

该文介绍了常见的基准网组建方法存在的缺陷,针对地铁隧道内监测区域较大情况,提出了一种基于自由设站与导线传递结合的多测站基准网组建方法,并以福州地铁6号线保护性监测工程为例,验证该方法的优越性和可靠性。结果表明,其坐标中误差均小于2mm,满足规范要求,对城市地铁等地下工程建设有较好的参考价值。

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 example,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.
