东京港大桥(Tokyo Harbor Bridge)采用前所未有的巨型浮运沉箱锚固缆索。在东京港大桥,采用沉箱作为缆索的海面碇泊地。这是世界上最大的沉箱,其体积为21万立方码(约16.1万m~3),超过了以前的纪录保持者、支撑纽约市Verrazano Na-rrows大桥Brooklyn一侧塔楼的沉箱。东京沉箱平面尺寸为230呎×148呎(70.104m×45.110m);高度为167.3呎(50.993m);下沉至海平面以下152.6呎(46.512m)处。 Tokyo Harbor Bridge Uses the Giant Floating Caisson Anchor Rope. At Tokyo Harbor Bridge, a caisson is used as a cable mooring surface. It is the largest caisson in the world with a volume of 210,000 cubic yards (161,000 m 3), surpassing previous record holders and supporting caissons in the towers on the Brooklyn side of the Verrazano Na-rrows Bridge in New York City. Tokyo caissons have a surface dimension of 230 ft x 148 ft (70.104 m x 45.110 m), a height of 167.3 ft (50.993 m), and sink to 152.6 ft (46.512 m) below sea level.
