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.

• 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。
