山西陵川龙岩寺中央殿大木尺度设计解读

Title Interpreting the Dimensional Design of the Wooden Structural of the Central Hall of Longyan Temple in Lingchuan County,Shanxi

基于201 0年5月保护工程基本完竣时综合运用三维激光扫描和手工测量针对山西陵川龙岩寺中央殿大木结构开展的采样式测绘,清华大学建筑学院师生得以尝试分析推导大殿木构尺度设计。研究表明:该建筑采用309毫米长营造尺,材厚为3.75寸,统计数据未能揭示单材广取值;斗栱总出跳60分°,结合架道尺度形成清晰规律,进而影响柱头平面设计;斗棋下昂整体呈折线形状,为很少见的早期下昂造做法。

Based on the combination of 3D laser scanning and traditional architectural survey of the central palace of Longyan Temple in Lingchuan County of Shanxi Province upon the completion of preservation,the team from the School of Architecture of Tsinghua University ventured to analyze the dimensional design of wooden structural of the building.It demonstrates that this building adopted 309 mm as a construction ruler(yingzao chi)with the thickness of cai in3.75 cun,while it fails to reveal the regulation of the length of cai.The extension of the bracket units measures 60 fen,which in combination of structural sizes regulates its plan layout.The lower cantilevers of the building are designed to be of shape of broken line,rarely seen in other contemporaneous examples.
