“凑合”的妙用——基于木建构的利川永顺桥适宜性研究

Harmonious Wisdom:The Suitability of Yongshun Bridge in Lichuan Based on Wood Tectonic

利川永顺桥是鄂西南地区现存唯一一座木伸臂梁与八字形撑架组合式木拱廊桥,是当地匠人在面对大跨挑战且已有技术、经验不足的情况下,“凑合”了几种既有结构技术实现的一次创新。通过介绍永顺桥的基本情况,分析其产生的背景,并从木建构的角度解析匠人们在面对材料、结构、建造施工等问题时所采用的构造方法,以此分析永顺桥的适宜性,以期对永顺桥的维修保护及价值开发有一定的启发。

Yongshun Bridge in Lichuan is the only timber arch covered bridge in southwest Hubei,which comprises stretching timber beam and inverted v-shaped brace.It is a creation made by the local craftsmen through coordinating several existing structural technologies,in the face of cross-challenges and with insufficient technical experience to cope with them.Through introducing the basic situation of Yongshun Bridge,this paper analyzes the background of its production,and from the perspective of wood tectonic,analyzes the construction methods used by the craftsmen in the face of the problems of material,structure and building,in order to explain the suitability of Yongshun Bridge.The research results have some value for the maintenance protection and value development of Yongshun Bridge.
