Abstract
The nearly finished Xinghai Bay Bridge at the southern seaside of Dalian in China is a long-span, double-deck, cross-sea suspension bridge. This bridge is the largest span highway double-deck suspension bridge with anchorage at sea in China. In view of the particular problems posed by the surrounding conditions, functional requirements, and aesthetic considerations, this project required a special structural design and innovations in construction technology. These innovations—including the steel truss design and erection process, the main cable-anchoring strategy, and the anchorage foundation design and construction techniques—are detailed in this paper.
