摘要
淳安南浦大桥为一净跨径308m中承式钢管混凝土桁式拱桥,宽跨比较小,该桥拱肋的横向稳定是桥梁安全性的关键,介绍了该桥整桥模型试验的主要过程,包括试验模型的设计、加载系统,给出了全桥、半跨、水平加载等六种工况下模型试验的主要结果,得出的结论可供该类桥梁设计和施工参考。
Chun'an Nanpu Bridge is a concrete filled steel-tube half-tied through-arch bridge. The span is 308 meters and the width-to span ratio is small. The stability of arch ribs is of major bridge safety concern. The global model test process of Nanpu Bridge is introduced, including design of test model, loading system, main results of the test. The educed conclusion is believed to be useful for reference in design and construction.
