Abstract

The first multi-span suspension bridge which crosses a strait in Korea was constructed and opened to traffic in 2019. The bridge is located on the southwest coast of Korea which is famous for magnificent view of the Dadohae. It is notable for this bridge to introduce some ingenious technologies like PPWS main cable (breaking stress of 1960 MPa), in-marine anchorage with a composite foundation, and high-performance steel. Also, the graceful curve line of the cable enables this bridge to harmonize with the surrounding landscape. Together with this bridge, Korea which already had two large suspension bridges—one with a main span of 1,545m and another with 3D cable planes—became a country with the diversity of suspension bridge technology.

摘要

韩国首座跨海峡的多跨悬索桥于2019年建成并通车。该桥位于韩国西南海岸，以多多海的壮丽景色而闻名。值得注意的是，这座桥引入了一些独创的技术，例如PPWS主缆（断裂应力为1960 MPa），具有复合地基的海上锚固和高性能钢。同样，电缆优美的曲线使该桥与周围的景观融为一体。韩国与这座桥一起，已经拥有两座大型悬索桥，其中一座主跨为1,545m，另一座主跨为3D电缆平面，成为了一个拥有多种悬索桥技术的国家。
