Design and Construction of a Highway Double-Deck Suspension Bridge

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.

Research in Layout of Pavement Markings in Freeway Merging Area

“…As regards to principle of designing acceleration lane length, considering the high occupancy of large trucks in China, commonly it was separated to acceleration segment, waiting segment, taper and calculated respectively [11][12][13][14][15][16] ,namely vehicles accelerated to the merging speed, and then waited under this speed until the acceptable gap appeared , then finished the merging. Among that, the calculation of waiting segment was mainly using gap acceptance theory, the method was mature and lots of achievements have been obtained, which offset the deficiency of Chinese standard on designing acceleration lane length.…”
