Study On Underground Engineering Project Safety Risk Analysis And Control Countermeasures

Rail transit construction of our country is rapidly developing, the underground space development and utilization has become domestic important research subject, which is facing huge risk, how to safely develop underground space construction, ensure underground engineering project construction safety have been the important needs in current development. In order to guarantee the achievement of engineering construction goal, it is urgently needed effective implementation of the security risk management during the underground engineering project implementation process.Base on this, in order to ensure safety of the underground engineering project implementation, In view of the current existing a series of safety risks in the construction of underground projects, The paper has analyzed underground engineering project safety risk, at the basis of risk management, disaster assessment theories and methods, through the means of on-the-spot investigation, data collection and theory analysis, and carried out the specific research in the links of the control system of risk response, safety risk monitoring and security risk emergency management, has acquired the following results:1. It has a comprehensive and system analysis on all kinds of uncertainty risks during the underground construction project construction process, constructed the3d analysis model of underground engineering project safety risks. And has comprehensive analyzed the content, process, characteristics of underground engineering safety risk management, as well as the problems existing in the engineering practice.2. From the three aspects of comprehensive project safety risk management system, whole process safety risk control scheme, and dynamic security risk management information system, has constructed perfect, system, strict comprehensive risk response control system, and proposed construction technical countermeasures against the underground engineering safety risks. 3. It has drafted implementation plan of underground environment safety risk management, and detailed analyzed the mean, characteristic and controlling measures of underground safety risk monitoring.4. It has analyzed management strategies of safety risk emergency punishment of underground engineering, preliminary proposed ideas and methods of constructing underground engineering emergency safety risk management system and emergency disposal system in the underground engineering information process.
