|Dr. Robin Sham Discusses Art and Science in Long Span Bridges|
On March 29, 2010, Dr. Robin Sham, Global Director of Long Span and Specialty Bridges for AECOM, shared his first-hand experience in some of the largest bridge projects in the world in a presentation on "The Art and Science of Bridge Engineering."
His lecture included a discussion on the world's two longest cable-stayed bridges—Sutong Bridge in China and Stonecutters Bridge in Hong Kong—and a suspension bridge, Tsing Lung Bridge in Hong Kong.
Dr. Sham drew examples from his numerous project experiences to illustrate how specific problems were resolved. He explained and focused on how some of the daunting challenges in ultra long span bridge engineering are tackled, how successful endeavors in integrating design and construction are performed, and the role of technology in supporting our quest to further advance bridge engineering for the benefit of mankind.
With a main span of 3,570 feet (1,088 meters), Sutong Bridge is the longest cable-stayed bridge in the world. The structure opened on May 25, 2008 and faced extraordinary challenges due to environmental factors and operational demands. The Sutong Bridge can withstand earthquakes and a marine monsoon subtropical climate—characterized by heavy rains, fog, typhoons and tornadoes. In addition, it can resist the impact of a 50,000-ton ship. Complex hydrology and deep bedrock problems were solved by pile caps resting on bored piles sunk into sandy soils. The bridge was the winner of ASCE's 2010 Outstanding Civil Engineering Achievement Award.
Stonecutters Bridge is the longest of its type in the world, with two steel-concrete composite mono-towers carrying a main span of 3,340 feet (1,018 m) and an overall length of 5,236 feet (1,596 m). Stonecutters Bridge is a major part of Route 8 between Tsing Yi and Cheung Sha Wan, straddling the Rambler Channel at the entrance to the busy Kwai Chung Container Port. The bridge deck is comprised of steel in the main span and prestressed concrete as well as steel in the back spans; wind tunnel tests were carried out to investigate rain-wind induced vibrations with aerodynamic consideration of overall bridge. The bridge opened on December 20, 2009.
The Tsing Lung Bridge is a suspension bridge design with a main span of 4,652 feet (1,418 m). The total length of the bridge is 6,247 feet (1,904 m) and the width is 174 feet (35 m). It carries a dual 3-lane of carriageway with hard shoulders in each direction. The Tsing Lung Bridge is a single-span box girder suspension bridge over the Ma Wan Channel. It spans across the Ma Wan Channel connecting North Lantau and Tsing Lung Tau on Route 10 in Hong Kong's Special Administrative Region. The superstructure deck is comprised of twin-box vented deck, connected with transverse cross beams at intervals along the deck.Dr. Robin Sham received his doctorate from Imperial College, London, and has pursued with passion a career in bridge engineering, one that spans over 30 years and several continents. A staunch advocate and practitioner in the art and science of bridge engineering, he has been involved in numerous large bridge projects, including the:
Dr. Sham has contributed to planning, procurement, design, construction and research and development, and has published widely on different aspects of bridge engineering.
