摘要
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,风力较大。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和变形,可为桥梁施工和控制提供参考。
Heigou bridge located at the exit of canyon is a PC continuous rigid frame bridge with 150m-span and the location has strong wind. Building its model by unit method, simulation the process of bridge construction, research its structure dynamic performance and the stress and the shape changed under wind load can give reference for construction and controlling bridge.
