Study of the Restoration Method for the Royal Palace of Hue, Viet-Nam

本研究旨在搜集有关越南顺化皇宫修复方法的学术资料，并与顺化古迹保护中心合作，建立修复与保护的方法论。从建筑风格的分类、理念、设计方法、生产群体和制造技术等方面进行比较研究，探索帝王建筑的特色形象。有必要建立一个与现场管理人员、研究人员和工程师联系的整体程序。我们计划调查，开始保护和修复项目，重点是这个观点。1996年，我们对皇城的立地平面图进行了测量制图，并对其进行了分析。根据场地规划方法假设的网格系统分析结果，我们假设砂砾为4240mm单位。其次，我们测量了忠庙和鸿庙，研究了柱径与跨距的比例和跨距的下降，我们检验了使用柱径的规划方法。1997年，我们的工作重点是皇家建筑的测量调查和皇帝陵墓的普查。同时，我们还进行了以下工作。(1)对装饰瓷砖进行拍照和分类(2)收集现场木构件的接缝信息和对木匠的工具分类(3)将史料转换为电子信息，整理皇宫建筑史。1998年，我们继续对皇陵进行测量，并分析了趋势。因此，我们假设设计单元在380mm到390mm之间。同时，我们用传统的施工工艺制作了寺庙的1/10比例模型。

Purpose of this study is to gather academic information for the restoration method of the Imperial Palace of Hue, Vietnam, in the Nguyen Dynasty, and to establish the methodology of restoration and conservation with the cooperation of Hue Monuments Conservation Center. We would like to explore the characteristic image of Imperial architecture by the comparative study focusing on classification of architectural style, idea, design method, productive group and technique of manufacture.It is necessary to establish a total program to connect with the field manager, researcher and engineer. We planed the investigation to start the conservation and restoration project, which focus on this point of view.In 1996, we measured the site plan of Imperial city to make drawings and proceeded the analysis of it. As to the result on analysis of the grid system which supposed by the site planning methodology, we assumed a grit is 4240mm unit. Secondly, we measure both of Tieu Mieu and Hung Mieu temple for the study on the proportion between diameter and span of columns and declines of span, we examined the planning method using a diameter of column.In 1997, we focused on measurement investigation of Imperial architecture and general survey of Emperor's mausoleums. Simultaneously, we also proceeded the work as follow.(1) Taking photos and classification of decorative tiles (2) Gathering information of the joint of wooden members at the site and classification of tools to carpenter (3) Converting historical materials to electronic information and arranging on the history of Imperial palace architecture.In 1998, we continued the measurement on the Emperor's mausoleums and analyzed the tendency. As a result, we assumed that the designing unit settle on from 380mm to 390mm. Simultaneously, we produced the 1/10 scale model of a temple with the construction process by traditional procedure.
