叠拱木桥的建筑特点

Building Characteristics of Timber Bridge Consisting of Superimposed Arch

提出叠拱结构模型，并探讨其在建筑工程中的应用潜力．文中采用理论分析与实物检测相结合的方法，确定叠拱在古今中外各类结构中的特殊意义，同时分析其在现代大跨度建筑中的实际应用．

A model of superimposed arch structure is proposed:and the latent capacity of its application to constructional engineering is explored.By combining theoretical analysis with object inspection,the specific significance of superimposed arch in various structures at all times and in all lands is determined.It has been applied to modern large-span building as an attempt.
