| In the tunnel construction, tunnel ventilation facility costs account for a large proportion,ventilation scheme is not only directly related to the construction of tunnel engineering costand scale, at the same time have become one of the main factors of tunnel technologydevelopment, but also directly affect the later operation safety service level and economicbenefits. But at present domestic has developed a number of ventilation calculation andsimulation software to do not have comprehensive properties.In order to design integrated tunnel ventilation software, the establishment of a largeamount of information in the database as the background of ventilation calculation software, avery necessity and significance. So the first part of this article mainly introduces and analyzesrelevant database design and ventilation; the second part of several ventilation places requiredair quantity was analyzed and discussed in detail, analyses the situation of tunnel ventilationin tunnel construction needs to consider, according to the formula given during theconstruction of the tunnel required air volume, analysis and discussion the tunnel operationventilation calculation of the main practice. Especially for the highway tunnel ventilationconditions needed done in-depth discussion; the third part, analysis of tunnel ventilationcontrol system of basic theory and mathematical model, in summary our country tunnelventilation intelligent control technology research and development situation of foundation,which is based on the design of artificial intelligence theory of tunnel ventilation intelligentcontrol system, according to the tunnel the wind velocity, wind direction, CO, VI datainformation and a blower to the corresponding control scheme, the tunnel fan open, stop,reverse control operating state. The system must be equipped with normal conditions ofventilation control and fire under conditions of ventilation control function. |
