A construction project of Incheon 2nd bridge, which is connected between the Incheon Song-Do New Town and the Incheon International Airport in Young-Jong-Do, have been proposed by the private capital in 1999. But the optimal span width in the bridge main span have not been decided in spite of the three investigations into the feasibility of ship's safe transit in this planned bridge. In this paper, we study the economic analysis on port operational efficiency according to traffic schemes, me-way or two-way of vessels over 10,000G/T, in the bridge main span of this bridge. In this comparative result, total queueing time due to the one-way in the bridge main span is evaluated 20,362 hours in 2011 and 24,544 hours in 2020. Therefore the demurrage cost and the accumulation cost of freight are evaluated 19.7 billion won in 2011, and 23.3 billion won in 2020, then total accumulated costs during 33 years from 2008 until 2040 are evaluated about 768..9 billion won.

국내에서는 원활한 물류 수송과 도로 이용자의 편의를 위한 해상교량 건설 등 대규모 해상공사가 활발하게 추진되고 있다. 하지만 항만 및 주요 항로를 횡단하는 해상 교량과 시설물이 해상이용자의 통항 안전과 효율성에 대한 충분한 고려 없이 경제적인 측면만을 부각하여 건설되고 있다. 이로 인해 VTS 관제구역내 위치하는 4~9년 공사기간의 대규모 해상공사와 해상교통안전 확보를 요구하는 해상교통관제센터 및 선박운항자의 어려움이 반복되고 있는 실정이다. 이에 본 연구에서는 경인항VTS 관제구역에서 진행중인 영종도와 청라를 잇는 제3연륙교 건설의 해상공사가 해양사고 등 선박교통 위험성과 VTS 업무에 영향을 미치는 요소를 살펴보고, 이에 대한 대응 방안을 고찰해 보았다.

But the optimal span width in the bridge main span have not been decided in spite of the three investigations into the feasibility of ship's safe transit in this planned bridge. In this paper, we study the optimal main span width according to the traffic volume in the future traffic and the ship maneuverability of maximum size aspect. The result cf this study, Incheon 2nd bridge main span design is required to design two-way traffic scheme and 1,000m span width, which will satisfy the safe transit from the viewpoint of the traffic volume in the future traffic and the ship maneuverability maximum size.

Field measurements and numerical simulations using EFDC model were performed to quantify the changes of water circulation near Gusipo coast located in the Yellow Sea of Korea to estimate the impact of the construction of the coastal structures (jetty, groin, Gusipo port and bridge). The model predicted tide and tidal currents agreed reasonably well with the measurements. The maximum currents during spring tide near the Gusipo Beach (GB) have the range of 20~40 cm/sec whereas those off the GB range from 60 to 80 cm/sec. The typical patterns of tidal current show parallel with the local isobath. Tidal currents flow northeastward during the flood tide whereas the currents during the ebb tide flow southwestward. The current speeds at shielded waters after the construction of coastal structures strongly decreased as compared with those before the construction. The tidal volume due to the construction of coastal structures was estimated using the depth averaged velocity for 24 hours of spring tide. Tidal volume after construction of coastal structures was compared with initial state (before construction). Tidal volume at present state (after construction of jetty, groin, Gusipo port and bridge) decreased by 28.4% as compared with that of the initial state. The volume after construction of jetty and groin decreased by 21.3%, and the volume after construction of Gusipo port and bridge decreased by 9.8%.
