摘要
小沙湾黄河特大桥是一座主跨440 m的混凝土主梁斜拉桥。由于东西侧索塔高低差别大,桥梁在结构震型上具有一定的特殊性。该文介绍了其减震设计,通过不断地调整阻尼器阻尼参数,最终使高低塔都达到较好的减震效果。
Xiaoshawan Huanghe River Bridge is a concrete beam cable-stayed bridge with 440-m span.The bridge has a certain specificity of structural vibration because of great height difference of the east and west cable pylons.The article introduces its seismic design of continuously regulating the damp parameters of damper and finally making the high and low pylons achieve the better damping effect.
