A study of the ancient domical architecture in Near Middle East by use of the 3D digitalmeasuring techniques

作者对约旦、安曼附近的Petra、Nuweijis和Jerash的West Baths的球形三角悬挂穹顶进行了建筑实地工作，并对其形式和建造日期进行了分析。结果，以下几点得到了证实。佩特拉(公元1世纪下半叶)的浴池不能被接受作为悬垂穹顶的备选方案，因为它在国内并不具备所有的悬垂元素。安曼附近的Nuweijis(公元2世纪中叶)和杰拉什的West Baths(公元2世纪3/4)都是用切割的石材voussoir建造的，所有元素都有足够的悬垂穹顶。新的测量证实，这两个纪念碑都有真正的球面三角形悬垂。特别是阐明了努维吉斯的下垂穹顶多为完美半球。

The author made architectural field works of spherical-trianglependentive domes in Jordan; Baths at Petra, Nuweijis near Amman and West Baths at Jerash,and analyze their form and construction date. As a result, the following points areconfirmed. Baths at Petra (second half of the 1st century) is not acceptable as ancandidate of pendentive dome, because it has not all elements of pendentive domesatisfactorily. Nuweijis near Amman (mid-2nd century) and West Baths at Jerash (thirdquarter of the 2nd century) are both made of cut stone voussoir and have all elementsof pendentive dome adequately. New measurements confirm that both monuments have truespherical-triangle pendentive. Especially, it is clarified that pendentive dome ofNuweijis is mostly perfect hemisphere.
