再谈义县奉国寺大雄殿大木尺度设计方法——从最新发布资料得到的启示

2008年,中国文化遗产研究院、天津大学等单位结合2004年以来实测工作,公布了辽宁义县奉国寺大雄殿的测量数据和研究成果;2011年,文物保护界又将1988年大雄殿大修过程中详细测量所得的构造图纸、数据和病害全面公布;2010年,中国文化遗产研究院、清华大学等单位使用三维激光扫描技术开展了补充测量工作。对比三份实测数据,通过结构几何解析结构的认识,本文尝试回顾关于斗拱设计、屋架结构设计和材分o与营造尺配合等方面假说,尝试证实、修正、调整先前假说,进一步厘清原始设计。

More on The Design of The Large Timbers in The Structure of Daxiong Dian(Hall)of Fengguo Temple of Yi County with The Enlightenment from The Latest Research Available

In 2008,a series of mathematical data derived from a survey of the large timbers in the structure of Daxiong Dian(Hall)of Fengguo Temple in Yi County of Liaoning province that had been underway since 2004 was released by Chinese Academy of Cultural Heritage and Tianjin University and other institutes working together.In 2011,a number of collected materials of structure drawings,measurements and disease condition records from the renovation of the Hall in 1988 got issued by the organization of historical heritages protection.In 2010,Chinese Academy of Cultural Heritage and Tsinghua University worked together to make a supplementary investigation of the Hall with 3D laser scanner to deepen some of the possible neglected details.By comparing the documentations from the three sources mentioned above and analyzing their geometric characteristics,the paper tries to confirm,correct and adapt the previous hypotheses regarding the designing of Dougong(bucket arches),roof truss structure and how cai-fen system(timber dimension module)fit architect’s measure,aiming to find out how the hall was on earth designed and constructed at first.
