中山市长江大桥引桥承载能力试验分析

Analysis on testing in capability of bearing weight in Zhongshan Changjiang bridge

介绍了中山市长江大桥引桥的静动载试验,并借助桥梁专用有限元计算分析软件M idas/C ivil和Ansys仿真模型,将理论分析计算值与试验实测值相比较,据此来验证在设计荷载作用下桥梁的整体受力性能,并作为桥梁竣工验收的依据。

In this paper the static and dynamic load test in Zhongshan Changjiang bridge is introduced.With the help of FEM（Finite Element Method） software Midas/ Civil and Analysis,which is especially applied for the bridge,the simulated model of Changjiang bridge in Zhongshan is built.We compared the test result with the theory count,that could verify the bridge beam with bearing weight under design and also it could be the foundation for bridge check and accept.
