THE NATURAL AERODYNAMIC OBSERVATION RESULTS OF THE CHAKVI-MAKHINJAURI ROAD TUNNELS

Authors

Abstract

The work presents the natural aerodynamic experimental observation results of Chakvi-Makhinjauri road tunnels. The air flow of the ventilation systems are measured, analyzed and presented in the form of graphs according to the following options: temperature, humidity of the area and variability of the air flow velocity in particular period of time and spaces. Moreover, the concentration variability of carbon monoxide in the ventilation flow is defined and results are provided in the form of graphs.  In addition, it is shown that at this location, 8 % of the wind (from the total quantity) incidence is directed towards Makhinjauri from Chakvi, which dramatically worsen the left tunnel’s natural ventilation conditions. According this aspect as well as the demanded norms of the ‘Construction rules and regulations’   the design, construction and operation of the mechanical ventilation system of the left tunnel is justified in accordance with its operational necessity of the combination with the existing right tunnel ventilation system exploitation.
