Research On Gas Tunnel Construction Safety Standardized Management

Abstract:At present, China road traffic rapid development, the construction of a tunnel through the coal-bearing strata growing number of projects, the resulting gas accidents occur frequently, gas prevention and control and management problems have become more severe. Key personnel of tunnel construction workers, social workers and the lack of appropriate management personnel, an urgent need for a set of the targeted gas prevention and control technical specifications and safety standardization management system. Has so far, China Ministry of Railways preliminary work done in this respect, promulgated the "Railway gas tunnel technical specifications", but in other sectors as well as in the management of safety standardization is still in the blank. To this end, the theme of the study on the "gas tunnel construction of safety standardization management system, combined with the safety system engineering theory and analysis methods, the reliability of the numerical simulation, software development, as well as examples of verification means study, and obtained the following results:1、Given gas tunnel regularization of the tunnel construction process, and to predict their risk. Hazard theory, identify, gas tunnel construction there, three main categories of sources of danger, and to explore its vest in the construction process and causes.2、The basic ideas and implementation procedures the DFTA-SVM hazard evaluation method, through the impact on the source dangers inherent construction gas tunnel evaluation, access to the various sources of danger risk assessment level.3、The GO methodology gas tunnel safety monitoring system and ventilation system reliability model and SIMULINK simulation in Matlab software module The its reliability numerical calculation. The results show that reliability of gas monitoring system to500hours a ventilation system reliability to200hours for one cycle.4、Created based of of principle of safety system engineering, safety of the of gas tunnel construction of standardized management system, gives the specific content of practical safety standardization management and safety standardization manage files and standardization of construction safety evaluation forms.5、In VC++6.0software development platform, of development of the gas tunnel construction safety standardization evaluation software, rating from management elements to the whole process of grading. The software engineering practicality verification to good effect.
