Abstract

The Yi Sun-Sin grand bridge is the suspension bridge which connects Myodo and Gwangyang. It is over the main navigation channel of Gwangyang Harbor. South anchorage(AN1, Myodo side) of the bridge is designed as rock anchored type. It sustains using the resistance of the underground rock's mass in Myodo. As this type of anchorage can minimize the exposure of the structure, It is economically efficient and environmentally friendly. North anchorage (AN2, Gwangyang side) is designed as the gravity type. This anchorage is 68 meters in diameter and use its own weight to support. Instead of normal rectangular diaphragm wall, the circular shape diaphragm wall is adopted to the north anchorage. It doesn't need to use internal temporary facilities, so it can significantly improve the constructability of the structure.
