南方潮湿地区考古遗址迁移保护初探——以长沙国际金融中心建设工地考古遗址迁移保护工程为例

长沙国际金融中心建设工地考古遗址迁移保护工程是大遗址保护实践的有益探索,也是目前遗址保护与区域经济建设协同发展模式下较具现实意义和操作性的一种大型遗址保护途径。本次迁移保护工程是湖南地区首次遗址类不可移动文物大规模迁移保护,采用"表面加固"、"分段整体切割"、"探铲打孔底板嵌套插入隔断"、"聚氨酯发泡固型"四个步骤,对各类型遗存进行科学、完整的迁移保护,该技术在长沙首次成功运用,解决了潮湿土遗址迁移保护的饱水环境、遗址基层不稳定、安全施工等技术难题。希望为南方潮湿地区遗址、墓葬的整体迁移保护提供有益的借鉴。

Conservation of Archaeological Sites in Southern Humid Areas by Relocation: A Preliminary Examination of the Site Discovered at Changsha International Financial Center

The relocation of archaeological site discovered at Changsha international financial center is a meaningful exploration for the conservation of large-scale archaeological sites; it is also a practical and feasible approach to the conservation of large-scale archaeological sites amid the dynamical integration between conservation and regional economic development. The relocation project, as the first large-scale relocation of immovable cultural heritage in Hunan, with four technical phases, provides scientific-based and integral relocation and protec- tion for various types of cultural relics. The successful application of this technology in Changsha has solved three major challenges to reloca- tion of earthen site in a humid environment, includingfull water environment, unstable foundation, and safety of construction. We hope that this project will provide helpful information for future projects of integral relocation of archaeological sites and tombs in southern humid areas.
