APPLICATION OF MODERN CALCULATION TECHNOLOGIES FOR THE ANALYSIS AND FORECASTING OF THE THERMO-GAS-DYNAMIC STATE OF THE TUNNELS OF COMMUNAL ENTERPRISE KYIV METRO

The increased humidity of tunnel air in certain sections of deep tunnels (Fig. a) leads to failure of the equipment of electrical systems and degradation of the tunnel walls.

Solution to the problem. Reducing air humidity by optimally managing the ventilation system and selecting favorable outdoor air parameters throughout the year, as well as determining optimal tunnel ventilation schedules using a number of developed models (Fig. b-d), taking into account the thermal state of the earth mass around the tunnels, outdoor air parameters, condensation and evaporation of moisture and parameters of power equipment. This made it possible to determine the optimal schedule for the operation of the tunnel ventilation system throughout the year. The adequacy of the models is ensured by the use of periodic measurements of temperature, humidity and air velocity in the tunnels.
