摘要
介绍了茅草街大桥主拱圈1∶5节段模型试验,试验模拟大桥的施工过程,得到了在各种荷载工况下拱顶节段钢管混凝土拱肋的应力分布,并与理论值进行了比较,跟踪实测了混凝土徐变对内力重分布的影响。
A model test for this kind of bridge was carried out and the model scale is 1/5. The stress distribution at the top section of arch ribs in different load cases was obtained by simulating the construction procedure, and the timedependent stress in ribs due to the crecp was measured. The measured results are compared with the theoretical values, which give credible data to the design of this bridge and the model test of the same type bridge.
