瞿曇寺隆國殿=Longguo Hall of Gautama Monastery; 營造尺=the ruler for construction(Ying Zao Chi); 大木丈尺設計=the proportion of structure measurements of large timber construction; 斗栱構造尺度設計=the detail dimensional design for Dougong Bracket
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.
