观察与量取——对佛光寺东大殿三维激光扫描信息的两点反思

本文通过近期对山西省五台山佛光寺东大殿前檐斗棋三维激光扫描测量所得数据进行深入分析,并借鉴前人研究成果,结合近期相关案例研究,对其下层昂底与二跳华拱交互斗的交接关系以及构件形变对于数据量取和下昂斜度计算的影响等构造细节问题进行分析和讨论。

Based on the recently repeated 3D laser survey and previous observations,this paper discusses the east hall of Foguang Temple against the background of similar examples to clarify in detail the joint between ang and jiaohudou,a small bearing block placed on top of the ang to support a second bracket in a dougong.It analyzes the deformation of wooden components and the step-distance between them,which is crucial to the design of the ang pitch.
