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. Based on the literature [1], the results of a model test of Zhongshan No.1 Bridge are preliminarily analyzed. The test results show that the dynamic performance of the bridge is good and there is no obvious weak point. Under the condition of dead load and the most unfavorable load, The deflection, the horizontal displacement and the stress of the bridge are within the allowable range of the specification, the maximum horizontal thrust is small, self-balance can be achieved in both the forward and the transverse bridge, and the rigidity of each arch rib is relatively matched, indicating that the bridge design concept It is scientific and reasonable and generally safe.
