Currently China has entered a peak period of urban rail transit construction, Beijing alone, there are six metro project started in 2009 or will be started soon, with five lines under construction, a total of 11. Rail traffic engineering data management is an important part of the construction of rail transit, the completion of the record of a unit project dossiers, comprehensive rail project quality and acceptance, important documents to reflect the status of the project. Information management system can barely deal with the conventional engineering data management, but the long no standardized unified coding, nor solve the test paper problem with the thinking of computer management, data management can only be done by hand, low efficiency, accuracy poor, not well calculated, retrieval, storage and management. Therefore an urgent need for an appropriate set of software to solve data encoding and Test Paper, to solve this problem, the detailed analysis and design solutions. This paper first introduces the status quo of China's rail transit project data management through field research, analysis of the data management process, according to the principle of the computer code, develop no classified information on all rail transit construction projects, an effective solution to the demand for paper generating and encoding ; to meet the construction of the rail traffic management system, the reusability of supervision information, the system uses a mapping solution, the introduction of the tree, reducing the large amounts of data repeatability, reduce system memory requirements, and improve the The operability of the system, and read and write speeds. Second, the combination of field data management processes and software engineering principles through needs analysis, system analysis, overall design, system evaluation, such as object-oriented software development methodology to design and develop a set of rail traffic engineering data management system. In this system, through the design and development of engineering information management table page management, test paper management and system backup features make up for the lack of previous engineering data management system. Several test points in the test results show the system basically meet the demand for rail transit construction in the first-line data management. The article also apply data mining theory a theoretical analysis of data on the construction of urban rail transit construction, once a problem with the quality of the project will have a huge negative impact on the city's social, environmental, transportation and economic timely theoretical analysis of construction data and inseparable from the conduct of the construction building. Finally, with specific examples of the Xidan station tenders for the 2007 Beijing Metro Line 1740 meters actual construction inspection data and semi-structured data using clustering methods for data analysis, the first to adopt the idea of ??text mining rail transit project information construction quality construction data management system extracted data mining method, and then use the extracted data preprocessing, attribute reduction system shortest distance algorithm analysis of the construction quality of the inspection object, and final calculated grade information.
