摘　　要：通过对浙闽木拱廊桥的结构组成体系及几何构造的定性分析,指出相关文献把木拱廊桥桥拱结构描述为稳定高次超静定体系是不恰当的。用实例说明其结构体系存在几何瞬变和几何可变的可能,并讨论具有互承结构性能的编织结构体系的机动性。Based on the analysis of the geometric construction of wooden arcade gallery bridges in Zhejiang and Fujian province, the author contends that it is incorrect for previous literature to describe wooden arcade gallery bridges as multiple statically indeterminate structures. Based on the analysis of an instance, it can be concluded that the structural system of the wooden arcade gallery bridges is geometrically changeable or instantaneously changeable. Through reviewing literature, the geometric construction of braided structure with reciprocal structural performance is discussed in hope of providing a reference for further in-depth research regarding relevant technologies.
