三峡库区白鹤梁题刻原址水下保护工程设计

Design of underwater in-situ protection works for White Crane Ridge Inscription in Three Gorges Reservoir area

三峡水利枢纽工程建成后,水库正常蓄水位将提高到175 m,库区有大量的文物需要保护。白鹤梁题刻既是国家级文物,也是三峡工程文物保护的重点,由于其特殊的地理条件和保护要求,保护方案几经论证才最终形成。介绍了用"无压容器"概念修建白鹤梁题刻原址保护工程方案的设计理念及主要设计成果。工程于2003年2月开工建设,2009年5月建成开馆。这一极具创新设想的工程实施,成为世界上唯一的遗址类水下博物馆,为水下文化遗产的原址保护提供了成功的工程范例。

After the completion of the Three Gorges Project（TGP）,the normal storage level of reservoir will be raised to 175 m and a large amount of cultural relics need to be protected in the reservoir area.The White Crane Ridge Inscription is the national cultural relic and the key of cultural relic protection in TGP reservoir area.Due to the special geographic conditions and protection requirements,the protection schemes are formed finally after repeated proof.We describe the design idea and main design results of in-situ protection scheme of White Crane Ridge Inscription with the concept of ＂non-pressure vessel＂.The construction began in February of 2003 and the museum opened in May of 2009.It becomes the only relics-type underwater museum in the world and provides an example for the in-situ protection of underwater culture heritages.
