Scope

Scope: Operation railway engineering measurement; Main technical content: 1. A complete technical standard system for operation railway engineering measurement has been established, filling the gap in technical standards for operation railway engineering measurement in China. 2. Starting from the actual needs of operation railway maintenance, the principle of using geodetic methods for operation railway line measurement has been proposed. The line coordinates are used to calculate the mileage of operation railway lines, abandoning the traditional method of re-survey using steel rulers, which improves the accuracy and efficiency of line mileage measurement and realizes the one-to-one correspondence between the line coordinate system (mileage) and geodetic coordinates, laying the foundation for establishing an operation railway information platform. 3. The principle of treating data processing for ballastless track lines and data processing for ballasted track lines differently has been determined. The re-survey of ballastless track lines mainly focuses on relative positioning and smoothness detection, while absolute coordinates are mainly used to evaluate the settlement deformation of the line. Generally, the line is not subjected to large-scale track adjustment and leveling. Fasteners are adjusted according to the smoothness. The re-survey of ballasted track lines is processed by combining relative positioning and smoothness with absolute coordinate positioning, and the line is fitted in both horizontal and vertical directions. 4. The re-survey method, accuracy indicators, and adoption principles of operation railway precision measurement network have been clearly defined. The principle of combining regular survey with focus area monitoring in deformation monitoring has been proposed, and the requirements and methods for regular survey and focus area monitoring have been clearly and detailedly specified. 5. Combined with the development of modern surveying
