Abstract


21 century, with the continuous progress of science and technology, China's urban rail transit at high speed, punctuality, low energy consumption, low pollution, safety, comfort features such as passenger transport in cities to attract more than 80%. Major cities into the subway, the rapid construction period, along with the diversity of construction technology, cross-cutting, complexity and particularity of the construction environment, construction accidents have also been rising, so people have to attach importance to construction planning and construction methods and safety technology, and actively carry out disaster prevention and control of subway construction. In order to better achieve the purpose of safe construction paper using literature review, field surveys, questionnaires and other methods in the analysis of the previous Subway Construction disaster monitoring system based on the use of extension theory shield construction disaster monitoring system analysis and monitoring indicators, quantitative analysis, and ultimately achieve accurate monitoring, reduce accidents purposes. Details are as follows: 1. Pair Metro Shield of monitoring indicators and monitoring programs were analyzed. In summary, based on the theory, the paper shield construction monitoring of the various stages of the risk factors were analyzed to determine the Subway Construction monitoring running processes, and by monitoring the process to determine the need to monitor key indicators and key monitoring indicators between association rules, an indicator for the future lay the foundation Extension Analysis. (2) use of field research methods, Subway Construction disaster monitoring indicators of an empirical study. The use of expert interviews on the subway shield construction monitoring issues predictive analysis. By Subway Construction of field research, historical data and other relevant literature on monitoring indicators were analyzed, and through extension association rule mining techniques shield construction monitoring monitoring indicators for analysis, classification, the Metro Shield Structure Construction Monitoring indicators are divided into nine first-order terms, 37 second-order terms, then Extension Element analysis for quantitative indicators, and thus more clearly for risk monitoring. 3 through a subway construction segment shield construction of case studies, in accordance with the extension theory index association rule mining method for monitoring indicators of analysis. Extension to establish monitoring model to identify a certain section of the main shield tunnel construction of monitoring indicators. OK monitoring project, and its extension analysis, quantitative monitoring indicators, and thus the construction of a section of metro shield for accurate monitoring. 4 Through the Subway Construction monitoring system establishment, this article will use the G1 its comprehensive evaluation method, the use of G1 method in the evaluation of the advantages of indicators for monitoring indicators G1 method to identify system deficiencies affecting the larger metro shield construction risk factors, and promptly corrected, for the development of risk prevention measures lay the foundation; then screened for shield construction brings more important to monitor risk factors for the subway construction units and provide the basis for the owner and decision support.
