Abstract
The construction of long sub-sea tunnel does not provide the favorable condition for the installation of ventilation system to be used during construction, due to the construction space constraint. For the ventilation system required during construction, the artificial island where ventilation shaft is located is constructed at some location along the sub-sea tunnel route, which requires a high construction cost. So, it is intended, as much as possible technically, to minimize the construction of artificial island. But this requires a longer distance between ventilation shafts, there-by causing increased air leakage at the ventilation duct connection points, due to the higher fan pressure being required to deliver ventilation air. Previously the air leakage was studied as an important issue. In this study, the experiments were carried out to develop the improved duct connection method considering various conditions like tunnel length, etc. And its performance results with leakage rates are shown and compared to the “S” class leakage rate of SIA. As a result, the new duct coupling type of improved method is analyzed as applicable to such a 30 km long tunnel with the leakage rate of 1.46 mm 2 /m 2 , which is better performance than SIA leakage rates.
