【摘要】：敦煌莫高窟是世界上现存规模最大的佛教艺术遗址圣地,上世纪六十年代先后被列为全国重点文物保护单位和世界文化遗产。敦煌莫高窟的石窟空间体系作为一个重要的建造体系,保存了许多古老而又珍贵的壁画、塑像以及与佛教密切相关的历史文物信息。地仗层是壁画颜料层的载体,是颜料层与围岩层的“中介”,地仗层中的水盐运移与壁画保护息息相关,因而,在地仗层的传热、传湿性能上值得深入研究。本文试图通过现场调查和查阅文献来挖掘莫高窟地仗层的建造经验和技术,对地仗层的详细构造进行合理的量化和科学的诠释。从而用以指导后续对地仗层及壁画的更深层次的研究,最终达到保护文物的目的。在广泛查阅莫高窟研究现状,地仗层传热传湿特性的最新进展的基础上,完成了以下工作:对地仗层试样材料的热物理性能参数和湿物理性能参数进行了测试;对洞窟内的热湿环境进行现场测试;基于以上研究基础,最后运用WUFI-2D软件对地仗层的热湿传递过程进行模拟研究。本文实验数据均为第一手资料,为进一步的研究打下了坚实的基础,对于地仗层热物理性能参数和传湿特性的实验是国内首次进行的测试,研究得出的结论与现场观察到的壁画病害的表现基本吻合,证明研究具有合理性和实用价值。
[Abstract]:The Dunhuang Mogao Grottoes are the world's largest living site of Buddhist art. In -40s, it was listed as the national key cultural relic protection unit and the world cultural heritage. As an important construction system, the space system of Dunhuang Mogao Grottoes preserved many ancient and precious murals. Statues and historical relics closely related to Buddhism. The ground layer is the carrier of the paint layer of the fresco, the "intermediary" between the paint layer and the surrounding rock layer, and the movement of water and salt in the layer is closely related to the protection of the fresco, so the heat transfer in the layer of the ground battle is closely related to the protection of the fresco. This paper attempts to excavate the construction experience and technology of Mogao Grottoes through field investigation and literature review. Reasonable quantification and scientific interpretation of the detailed structure of the ground battle layer are carried out in order to guide the further study of the ground support layer and the murals, and finally to achieve the goal of protecting the cultural relics, so as to consult extensively the present research situation of Mogao Grottoes. On the basis of the latest progress in heat and moisture transfer characteristics of the ground support layer, the following works have been accomplished: the thermal physical properties and the wet physical properties of the sample material of the ground support layer have been tested, and the thermal and wet environment in the cave has been tested in the field; Based on the above research foundation, the simulation of the heat and moisture transfer process in the ground layer is carried out by using WUFI-2D software. The experimental data in this paper are all firsthand data, which lay a solid foundation for further research. It is the first time in China to test the thermal and physical properties and moisture transfer characteristics of the ground layer. The conclusion of the study is basically consistent with the field observation of the mural diseases, which proves that the research is reasonable and practical.
