山西应县木塔的尺度规律

Measure Regulation of the Sakyamuni Pagoda in Yingxian County, Shanxi Province

通过对山西应县木塔测绘数据的分析,在前人研究的基础上提出了尺度规律新的推定结果,进一步解释了每层各开间面阔的取值规律及木塔大尺度的比例关系.研究表明,山西应县木塔的尺度规律为模数制,基本模数为22.1cm,它控制了层高、每层通面阔和每层各开间面阔,使每层通面阔和每层各开间面阔的取值表现出简洁的递变规律.这一现象与日本飞鸟、奈良时期多重塔的规律相似,是我国唐宋时期古建筑存在模数制的一个重要例证.

By analyzing the measure data of the Sakyamuni pagoda in Yingxian County, Shanxi Province, a new measure regulation was put forward based on the former viewpoints. According to the new measure regulation, the change in the side length of each span of each story can be further explained. The research shows that the measure regulation of this Sakyamuni pagoda is a modulus system, and the basic modulus is 22.1 cm to control the height and the side lengths of each story and each span. Based on the basic modulus, the side lengths of each story and each span have a gradually changing and simple regulation. This phenomenon is similar to that of some ancient pagodas in the periods of Asuka and Nara in Japan and can be used as an important evidence to the existence of a modulus system in ancient buildings in the period from the Tang Dynasty to the Song Dynasty.
