摘    要:内蒙古集宁-丰镇高速公路上的黑沟大桥为主跨150m的预应力混凝土高桥墩连续刚构桥,位于峡谷出口处,风速较大。文章利用有限元方法建立其模型,模拟桥梁的施工过程,研究其结构动力学特性和风荷载作用下的应力及变形,为桥梁施工和控制提供参考。

关 键 词:刚构桥  风荷载  振动  有限元

Abstract:Heigou super-large Bridge,located at the exit of gorge with the higher speed of wind is a continuous prestressed concrete frame bridge on the higher piers with main span of 150m.The Bridge was modeled with finite element method to emulate the whole process of bridge construction as to do research on the dynamic performance of the structure,the stresses and deforma- tion under wind load,thereby providing a basis for the construction control.
Keywords:rigid frame bridge  wind load  vibration  finite element
