摘　　要：渝澳大桥主桥采用变截面PC连续刚构 ,跨径组成 96 +1 6 0 +96m ;引桥采用 2 4 .9～ 35m不同跨径的等截面连续梁 ,截面采用超薄、大悬臂、斜腹板形状与花瓶墩配合 ,达到轻盈、和谐、统一的效果。The main bridge of Yuao Bridge is PC continuous rigid frame with variable cross section, spans are 96m+160m+96m. Approach bridge is a continuous beam with varied spans (24.9～35 m) and uniform cross section. The cross section, in the shape of super-thinness, large cantilever, skew web, is in harmony with vase piers, which makes the bridge slim, graceful and harmony. This paper introduces specially the structural design characteristics and tests of the bridge.
