Design and Experimental Research of Xinghai Bay Cross-Sea Bridge in China

The Xinghai Bay Bridge is a cross-sea suspension bridge in Dalian, China. This bridge is the first suspension anchored in the sea in China. This paper introduce each structure composed of Xinghai Bay Bridge and sets out the anchorage slippage experiment. The girder, tower, main cable, hanger, cable saddle, anchorage and caisson foundation are presented. In addition, the friction coefficient between the gravel bed and the concrete caisson is determined with anchorage slippage experiment. The experiment results show that the dry friction coefficient is 0.520, and the underwater friction coefficient is 0.516. Water decreases the friction coefficient.
