Abstract


Shorter tunnel and underground engineering risk analysis and assessment studies history, especially the shield tunnel engineering, domestic primary stage, but has been more and more attention. And the tunnel disaster Treatment system research is in its infancy. With the constant expansion of tunnel and underground engineering construction, to carry out the tunnel and underground engineering risk assessment and disaster Emergency Treatment system integration research, it is particularly important significance. By studying summarize existing shield tunnel construction period common types of disasters, including the characteristics of the the shield tunnel out of the hole stage four common disaster and shield tunneling phase of the 11 common disasters, and incorporated into the risk analysis and assessment model, comprehensive evaluation and discussion. The same time, the data of these disasters, is also important the Shield Tunnel disaster Treatment system basic information. The main analytical research work to carry out the following aspects: First, focus on the mechanism of risk, risk analysis and assessment of the model, as well as the project's overall risk assessment. Fully tap the existing research data and research results, and the possibility of various types of risk of accident probability. Introduction of VaR as risk evaluation and risk indicators, and given the level of risk standards based on risk indicators. The second is to summarize the characteristics of common types of shield tunnel disaster, focusing on the 15 kinds of disasters phenomenon, the causes, prevention measures and Treatment program. Were discussed based on the database structure and content of the shield tunnel construction disasters Treatment System under the conditions of the risk assessment, risk management software and disaster Treatment system module. The initial development of the Shield the tunnel disaster Treatment System, has some practical value. This paper studies the findings include: (1) a comprehensive summary of the shield tunnel construction of the 15 kinds of disasters. , Respectively, of the phenomenon of the disaster, the causes, prevention measures, and Treatment Measures were summarized, to provide support for the Comprehensive Disaster Treatment System. (2) make full use of existing research data and research results to promote a quantitative evaluation of the shield tunnel disaster risk value and risk indicators two evaluation methods. The ③ proposed organic combination of the idea of ??the risk assessment system and the Disaster Emergency Treatment system, initially developed shield tunnel construction disasters Treatment System software with certain applicable value.
