隧道施工事故隐患分析与安全工程设计(3)
After finished the third chapter ventilation safety engineering design, this design still other accidents in the tunnel safety management technology measures discussed in this paper, summarizes the factors affecting the safety of tunnel construction control method and tunnel construction site safety management measures, and emergency rescue plans for the tunnel construction process, is the tunnel is the systematic and comprehensive analysis of the ground, for the tunnel construction safety technical improvement and innovation provides a powerful reference value, and for the tunnel construction has important practical significance.
In this design in the end, this paper made a comprehensive summary of and this design was discussed. This design from the aspects of practicability and maneuverability. Tunnel construction safety is always a nagging question of its security problems also emerge in endlessly, this requires that we can more and more engaged in the research of tunnel safety, engaged in tunnel safety aspects of the design can be more and more advanced, can engaged in tunnel construction technology is more and more mature, hope these can be achieved, in the near future for millions of tunnel construction personnel life insurance.
Key words：The tunnel construction；A hazard analysis；Safety engineering design；
