Research On Risk Integrated Management Of Metro Tunnel Engineering Based On Drilling And Blasting Method

Drilling and blasting method is formed gradually in the long-term practice of metroconstruction process. There are some features of metro tunnel engineering based ondrilling and blasting method such as the longer implementation time, the moreparticipants and the more risk accidents. The need of science risk management whichcan guide the project implementation is very urgent. In this thesis, the systemsengineering ideas, the risk management theory and the decision model have been usedto research the risk integrated management of metro tunnel engingeering.The mainresearch works are as follows:(1) Guided by the systems engineering ideas, the thesis discussed the theoreticalbasis of the risk integrated management of metro tunnel engineering based on drillingand blasting method. The time dimensional, participants dimensional and viewing angleof project have been analyzed.The main connotation of risk integrated management waselaborated.(2) The ideological connotation of hall systems theory has been used to build theintegrated system of risk management based on three-dimensional ofTime-Participants-Risk.The working mode and the form paradigm have been analyzed.On the basis of the above research, the thesis proposed the new risk identificationmethod based on the risk coordinate statistical table.(3) The risk coordinate statistical table has been used to identify the system riskand build risk identification list.On the basis of the risk list, the thesis restructured andsubdivided the risk domain. Selected the time dimensional as benchmark, thecomprehensive evaluation system of metro tunnel engineering based on drilling andblasting method has been build.(4) The thesis explored the excellent characteristic of ordered weighted averagingoperators and the non-additive measure of the weights of the metro risk index.Theweighting model based on the Shapley value has been build.Combined with grey systemtheory, the thesis explored the connotation of the metro risk management system and theapplicability of the grey system theory.(5) The thesis used the weighting method which combined the ordered weightedaveraging operators based on the combinatorial number and the Shapley value methodbased on the non-additive measure to determine the weight of the risk index.Grey system theory is used to define the measure of the metro risk. Combined thecombination weighting method and grey system theory, the grey cluster risk evaluationmodel has been build.(6) Combined wih the Qingdao metro line M1project, the three-dimensionalintegrated system, the comprehensive evaluation system of metro tunnel engingeeringand the grey cluster risk evaluation model have been used to analysis the specificengineering practice. At last, the thesis explored the key risk index of eachimplementation process.Combined with the construction technology of derlling andblasting method, the thesis proposed the control measures of the key risk.
