ABSTRACT

Many ancient brick structures have been recorded in the archaeological site of Sambor Prei Kuk. Most of these structures were considered to be built in the 7th century as religious facilities of royal city Isanapura and abandoned in the 15th century. Since then, the brick structures in this site had been covered by dense forest and suffered severe damage due to the tropical climate. This archaeological site was inscribed on the World Heritage List in 2017, and proper intervention is needed to preserve the remaining brick structures. The Sambor Prei Kuk Conservation Project carried out comprehensive research on the state of conservation for all 286 brick structures in this site. This project has developed a risk map, and carried out the survey of structural deformation and diagnosis of deterioration. Based on these surveys, the main causes of damage were identified: outward deformation of the base and foundation; thrust caused by the roof of the corbel arch; structural weakness at the door opening; fragmentation of brickwork by invasive vegetation; and impact of fallen tree. Finally, appropriate and acceptable restoration methods which can effectively stabilize and consolidate the brick structures to prevent further destruction while not negatively affecting the authenticity were discussed.

摘要

Sambor Prei Kuk考古遗址记录了许多古老的砖结构。这些建筑中的大部分被认为是在 7 世纪作为皇家城市伊萨纳普拉的宗教设施而建造的，并在 15 世纪被废弃。此后，该遗址的砖结构被茂密的森林所覆盖，并因热带气候而遭受严重破坏。这个考古遗址于 2017 年被列入世界遗产名录，需要适当的干预来保护剩余的砖结构。Sambor Prei Kuk 保护项目对该场地内所有 286 座砖结构的保护状况进行了全面研究。本项目制定了风险图，开展了结构变形调查和劣化诊断。基于这些调查，确定损坏的主要原因：基础和基础向外变形；由牛腿拱顶引起的推力；开门处的结构性弱点；外来植被破坏砖砌；和倒下的树的影响。最后，讨论了适当且可接受的修复方法，这些修复方法可以有效地稳定和巩固砖结构，防止进一步破坏，同时不会对真实性产生负面影响。
