Analysis Of Undergroung Building System Based On Air Supply And Smoke Exhaust

Abstract

Owing to rapid urbanisation, traffic issues etc., more and more underground space was used in the 21st century. Underground areas with different thermal, ventilating and lighting conditions can cause problems in terms of comfort, health and safety. Excessive moisture, heat transfer, excessive CO due to long-distance traffic tunnels blockage, difficulty in smoke exhausting and escape from burning, dangerous microorganisms, contaminants of radiation, psychological issues and so forth are all concrete issues. Underground air-quality control systems will be evaluated including ventilation technology, wetting technology, technology for natural energy usage, smoke mining, and air resistance reduction technology. Ventilation and ventilation may also be tested for smoke-proof / evacuation purposes. Work and findings were provided in the study of five new underground interchange buildings and the results are obtained. For the standard two-stage interchange construction, another study was conducted and the methodology and findings of this research are presented.
