在前人对万佛殿大木结构实测及所绘制的相关图纸的基础上,清华大学综合运用全站仪、三维激光扫描仪和手工测量对这座重要的早期木结构进行了精细的测绘工作。通过现有数据的分析,本文初步推算出古代匠人在万佛殿大木尺寸设计中采用了306毫米的营造尺,进一步分析了大木尺度设计的基本方法,讨论了该建筑的平面丈尺、斗栱、屋架等设计细节问题,并借助木材与碳同位素检测对建筑始建年代和遗存现状进行了分析与证实。 On the basis of the predecessors’ measurements and the related drawings drawn from the large wooden structure of the Wanfusidian, Tsinghua University comprehensively used total station, three-dimensional laser scanner and manual measurement to carry out the fine mapping work on this important early wood structure. Through the analysis of the existing data, this paper initially estimates that the ancient tradesmen adopted the 306mm construction scale in the design of the large wooden frame of the Wanfudin, further analyzed the basic methods of the design of the large wooden scale, and discussed the flatness, , Roof truss and other design details, and the use of wood and carbon isotope detection of the building was built and remains of the status quo were analyzed and confirmed.
