青海乐都瞿昙寺隆国殿大木结构研究补遗

An additional Study to the Large Timber Construction Work at Longguo Hall of Gautama Monastery,Ledu County,Qinghai Province

本文在总结前人关于青海瞿昙寺隆国殿大木结构研究成果的基础上,结合2009年使用三维激光扫描仪和全站仪进行的补充测绘,经过综合提取数据、统计分析,提出:1)隆国殿大木用尺316.5毫米;2)柱头平面采用简明的尺度设计方法;3)面阔、进深与柱高、通柱高之间不存在精确比例关系,而存在近似比例关系,反映出可能存在一种尺度控制设计。本文进一步将这种大木结构设计特点归纳为六个推论。

Based on the previous researches and a supplementary survey of the large timber construction work at Longguo Hall of Gautama Monastery(Qutan Monastery),Ledu County,Qinghai Province by using 3D laser scanner and Electronic Total Station in 2009,this paper suggests:a) the ruler(Ying Zao Chi)used in the timber construction of Longguo Hall is 316.5 mm long;b) the planes of Zhutou(the top of the column)were designed with the simple measuring method;c) a precise proportional relation between the building width,depth and the column height and the complete column height is unavailable,whereas there is an approximate proportional relation which reveals the probability of design of scale control.Besides,this paper further makes totally six deductions from these characteristics on the large timber construction work.
