Research on retesting technology of traverse control network in tunnel tunnels:Taking the Chongqing Section of Zhengwan Railway as an example
ZHONG Jiaqiang
Abstract：To ensure the safety and quality of tunnel construction,this paper takes the Chongqing Section of Zhengwan Railway as a case study and conducts an in-depth investigation into the re-surveying techniques of tunnel interior traverse control networks.The paper first introduces the general situation of the survey area and the design scheme of the elevation control network.It then elaborates on the re-surveying methods for tunnel interior control networks and proposes corresponding measures to address potential over-limit issues encountered during the re-surveying process.Through comparative and analytical studies of the data,suggestions for optimizing the re-surveying procedures and enhancing measurement accuracy are put forward.The results demonstrate that the application of advanced surveying technologies and rigorous re-surveying procedures can effectively improve the accuracy of tunnel interior traverse control networks,thereby providing a reliable technical support for tunnel construction.
