摘要
广州海印桥为主跨175m的双塔单索面斜拉桥,基于有限元软件对该桥进行静动力分析,介绍该桥的静动载试验,并依据有限元分析结果及静动载实测数据,了解及评价该桥当前的承载能力、自振特性和在运行荷载作用下的动力性能,为桥梁今后的管养与维护积累数据。
Guangzhou Haiyin Bridge is a cable-stayed bridge with 175 m main span,twin towers and single cable plane. The static and dynamic analysis has been conducted on the basis of FEM software. The static and dynamic tests of the bridge have been introduced,current bearing capacity,natural vibration characteristics and dynamic performance under operational loads of the bridge have been concluded and evaluated on the basis of FEM analysis and site tests results,which could be used as reference for administration and maintenance of similar bridges in the future.
