结合中国文物研究所(今中国文化遗产研究院)和清华大学的手工实测、清华大学2005—2006年对宁波保国寺大殿的三维激光扫描测量和手工补测,本文借鉴前辈学者对于保国寺大殿原始设计尺寸权衡的论述,在今天毫米级精度的测量数据和统计分析的基础上,得出以下结论:保国寺大殿设计营造用尺长313毫米;大殿木构架四围撩檐枋前后左右均采用精确到尺的整数尺度控制,前后撩檐枋间距5丈3尺,东西撩檐枋间距4丈8尺;大殿外檐斗栱材厚10分°,采用平出44分°、举高22分°的昂制,此斜度进一步用在了檐口椽的坡度上;大殿举折规律尚无法全面揭示,但其总举高度或牛脊槫至脊槫的举高可能遵循了1/3的殿堂起举做法。通过上述的分析与结论,本文强调提高古建筑测绘数据质量和数据精度的重要意义及深远的科研前景。
Combining the manual measurement of the China Cultural Heritage Institute (now the Chinese Cultural Heritage Institute) and Tsinghua University, and the three-dimensional laser scanning measurement and manual measurement of the Baoguo Temple Hall in Ningbo from 2005 to 2006 by Tsinghua University, this article draws on previous scholars to discuss Baoguo Temple. Based on the analysis of the size of the original design of the main hall, based on today’s measurement data and statistical analysis of millimeter-level accuracy, the following conclusions are drawn: The length of the building of the Baoguo Temple hall is 313 mm in length; the wooden structure of the main hall is surrounded by a quadrant. Adopting an integer-scale control with precision to the ruler, the pitch between the front and rear is 5 feet and 3 feet, the distance between the east and the west is 4 feet and 8 feet, and the thickness of the coffin is 10 minutes, and the height of the coffin is 44 minutes, and the height is 22 The degree of subordination, this slope is further used in the slope of the mouth ; ; ; ; ; 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大 大The palace started its approach. Through the above analysis and conclusions, this paper emphasizes the importance of improving the quality and data accuracy of surveying and mapping data in ancient architecture and its far-reaching scientific research prospects.
