Abstract
In order to solve the problem of central line incompatibility and layout inconsistency caused by the establishment of two construction plane control networks during construction, this paper employs relative relation analysis between different coordinate systems,alignment analysis of central line layout in two different coordinate systems,theoretical central line analysis in different coordinate systems to access construction impacts based on the ballastless track in an extra-long railway tunnel. The results show that there is no significant difference between the independent coordinate system theoretical central line and the line coordinate system theoretical central line, and the application of the line coordinate system theoretical central line in line construction and track laying is practical and effective.关键词
