Abstract: According to Regulation of Budget Estimation for Hydropower Projects (2013 Edition), the construction ventilation cost for underground projects is estimated as a part of total construction cost, and included in other temporary construction cost. However, for large underground caverns with high ventilation cost, it should be estimated separately based on the actual situation. Taking underground water diversion and power generation system of Baihetan hydropower station as an example, this paper makes a preliminary analysis and calculation for construction ventilation cost of large underground caverns.

Key words: underground caverns, construction ventilation cost, Baihetan hydropower station
