自古以来桥梁就在我国的交通方式中占据着重要地位。我国桥梁的历史悠久,种类丰富。但据了解我国主要的桥梁结构都存在自重大,施工复杂的问题。因此若是能有一种自重轻,施工便捷的桥梁形式,对我国的桥梁建设工作是很有利的。本论文通过对汴水虹桥和闽浙木拱桥进行结构分析,并根据笔者对两种结构的理解提出将两者优点集于一身的虹桥式木拱桥结构。并利用SAP2000软件分别对三种模型进行模拟分析,根据分析结果总结新模型的优点,并制造简单的实物模型对其进行加载实验以验证其优点。
Since ancient times, bridges have played an important role in the transport modes of our country. Our bridges have a long history and rich variety. However, it is understood that the main bridge structures in our country are self-important and complex in construction. Therefore, if there is a form of bridge that is light in weight and convenient in construction, it will be very beneficial to our bridge construction. Based on the author’s comprehension of the two kinds of structures, this paper proposes the structure of the Hongqiao-type wooden arch bridge which integrates the advantages of the two. The simulation analysis of the three models was conducted by using SAP2000 software. The advantages of the new model were summarized according to the analysis results, and a simple physical model was made to carry out the loading experiment to verify its advantages.
