桥梁模型试验在宋金时期浮桥建造中的应用

为了探讨宋金时期中国桥梁建筑技术,分析了桥梁模型试验在宋金锂期浮桥建造中的应用。分析认为,北宋采石浮桥的建造已经出现了足尺模型,金初的蒲津渡浮桥更是实现了足尺模型向缩尺模型转换的关键过渡,而南宋时的中津浮桥系统地运用了现代桥梁模型试验的诸多理论。

Application of bridge model test on construction of pontoon bridge in Sung and Jin(Jurchen)Dynasties

In order to find the bridge construction techniques in the Sung and Jin（Jurchen） Dyn-asties,this paper discusses the bridge model tests at that time.The research results show that the full-scale model were emerged in the construction of Caishi pontoon bridge in the Northern Sung Dynasty,and then the full-scale model of bridge changed into the reduced-scale in the construction of Pujindu pontoon bridge in the early of Jin（Jurchen） Dynasty.Besides,lots of modern theories about the bridge model test were used in the construction of Zhongjin pontoon bridge in the Southern Sung Dynasty.All these have strongly indicated that the technological level of bridge was developed greatly at that time.
