The present invention discloses a ventilation system for an underground structure which can internally supply fresh outdoor air by individually sucking and discharging air through fans of underground shafts in the underground structure such as an underground parking lot, underground warehouse, subway space, underground sporting place and underground hangar. The ventilation system for the underground structure includes air supply side fixed frames installed in air supply holes of each floor of the underground structure along one side shaft of the underground structure, air supply fans installed on the air supply side fixed frames toward the air supply holes, air exhaust rooms for forming air exhaust spaces on each floor of the underground structure, air exhaust holes being formed therein toward the other side shaft of the underground structure, air exhaust side fixed frames installed in the air exhaust rooms, and air exhaust fans installed on the air exhaust side fixed frames toward the air exhaust holes. The ventilation system for the underground structure cuts down initial expenses for installing the air supply/exhaust fans, fan rooms, large fans and an apparatus room, efficiently uses the underground space, reduces noises, cuts down maintenance expenses, and optimizes ventilation in the underground structure, by sucking fresh outdoor air and discharging used air on each floor with a low price and a simple structure.
