摘要
金水桥是具有重要历史意义的石拱桥,利用ANSYS有限元软件,选取混凝土单元Solid65,按照现行规范,进行了抗震分析。结果表明金水桥在8度地震作用下不会发生破坏,在遭遇9度地震作用时会发生局部破坏,特别是拱圈1/4和拱顶处,建议对拱圈石块的缝隙进行局部的抗震加固。
The Jinshui arch bridge before Tian＇an Men is important for its age and historic interest. Its material is granite rock mainly. It is critical for the whole bridge to have the ability of resisting a certain earthquake. The cracked condition of the rock has been analyzed using ANSYS program through selecting the element of Solid65. According to the latest construction code, response spectrum analysis has been done for the bridge, and the destroyed conditions of the modal under the earthquake force is got. The advice is given for local mending the bridge.
