摘　　要：青岛海湾大桥是连接主城区与经济开发区的跨海交通工程,主跨采用三跨连续钢箱梁悬索桥(586m+1652m+586m),双向六车道2×3×3 75m设计,通航净空为双向航道净宽1046m,净高65m,防撞标准按32万t级油轮实载28万DWT进行计算比选,抗风标准为v=34 5m·s-1,抗震烈度为Ⅵ度。文章介绍该桥的方案设计、工程造价、效益分析及财务评价。Qingdao Gulf Bridge is a crosssea road bridge project connecting the main city area with the economic development zone. The main span is a suspension bridge with three continuous steelbox beams (586 m+1 652 m+586 m). It is a bidirectional sixlane road bridge (2×3×375 m). The clearance of the bridge for navigation is 1046m in net width and 65 m in net height both ways. The anticollision standard is decided on the case of a 32 t oil tanker loaded with 280 000 t DWT. The wind resistant standard is v=345 m·s-1. The antiseismic standard is Ⅵ degree. This paper introduces the design, the engineering cost, the costbenefit analysis and the financial estimation of the bridge.
