| 摘 要： | 在分析闽浙木拱廊桥结构发展背景和营造特点的基础上，总结了国内外对闽浙木拱廊桥木材材性、受力系统、传力机理、节点等方面的研究方法和研究内容。 文献分析表明，廊屋等竖向荷载对廊桥整体稳定有利，但廊桥抵抗横向荷载的能力不强。 该体系中构件受力以轴力为主，各个系统之间相互搭接传力，拥有拱桥的受力特性，是现存廊桥最为成熟的结构形式。 通过综述研究指出闽浙木拱廊桥受力系统和节点是对结构受力性能影响的关键问题，为廊桥的保护修缮和新建改造提供理论依据。

| Abstract: | Based on the analysis of the structural development background and construction characteristics of timber arch covered arcade bridges in Fujian and Zhejiang provinces, a summary was made of the domestic and foreign research methods and contents of timber properties, stress system, force transmission mechanism and joints of such bridges in the two provinces. Literature analysis shows that the vertical loads such as corridor and house loads contribute to the stability of the bridges, but these bridges show a poor performance in resisting the transverse loads. Axial force mainly exists in the component of its system, and each system overlapping with each other could transmit forces. It has the mechanical characteristics of arch bridges, and is the most mature structure of existing ancient gallery bridges. Through the review, it is pointed out that the stress system and joints of these bridges are the key problems affecting the stress performance of the structure, and provides a theoretical basis for the repair, protection and construction of these bridges. |
