Structure and Construction Techniques of Historical 'Suspended Three-Sided Arch' Bridges along the Bijiang River in Yunnan Province:A Case Study of Yongji Bridge in Liandeng Village
摘要
Abstract
This article discusses the structural characteristics and technical principles of the 'sus-pended three-sided arch' found in historical bridges along the Bijiang River in Yunnan Province.Taking the Yongji Bridge in Liandeng Village,Yunlong County,Dali Bai Autonomous Prefecture as an ex-ample,the artcle identifies the bridge's use of tie rods in its three-sided arch that aligns with truss structure principles.Such structure and construc-tion method are rare in traditional Chinese wooden architecture.Neither the construction techniques nor the heritage values of this bridge type have been sufficiently studied,resulting in frequent mishan-dling in contemporary repairs.Using construction details as an entry point to structural discussions,the article explores the mechanical principles,con-struction techniques,and craftsmanship thinking by examining the characteristics of the bridge's wood-working joints.It reveals the technical relationship between the bridge's special truss system and the chuandou(post-and-tie)architectural tradition in southwestern China,aiming to provide a technical reference for the future conservation and repair of bridges of this kind.关键词
