摘    要:在文献1]的基础上,对中山一桥模型试验测试结果进行了初步分析.测试结果表明:该桥动力性能较好,无明显的薄弱部位;在恒载及最不利荷载作用下,模型桥梁的挠度、水平位移、应力均在规范允许的范围内.最大水平推力较小,在顺桥向及横桥向均可以实现自平衡,各拱肋刚度是比较匹配的,说明该桥设计构思是科学合理的,总体上是安全的.

关 键 词:空间组合拱桥  模型试验  测试结果

Abstract:On the basis of Reference 1, the experimental results of model of Zhongshan First Bridge are briefly described in this paper. Fundamental experimental result is briefly analyzed. It is showed from the test results that the bridge has good dynamic performance, and has no obvious frail part; deflection, horizontal displacement and stress are all confined in the range permitted by code under the dead load and worst living load; horizontal thrust, which is self-balanced in the longitudinal and transverse direction, is low; stiffness of the various arch ribs is matching, thus the design of the bridge is proved to be reasonable and safe.
Keywords:beam and arch combined bridge  model experiment  experimental result
