目的-盐的风化作用是中亚土遗址最常见的腐蚀因素之一，它是墙表面水分蒸发的结果。在挖掘之后不久，Ajina Tepa佛教寺庙的土墙和佛塔（公元7 - 8世纪）由于缺乏保护和表面侵蚀而开始恶化。保护工作规划中最重要的问题是了解这种机制，并减少盐风化对结构破坏的影响。本文旨在探讨这些问题。设计/方法/途径-选定的墙壁上的蒸发分布和盐的类型进行了研究。此外，墙壁和佛塔的三维记录进行了数字摄影测量方法。结果-人们清楚地发现，在该网站的盐风化的强度很高，一些盐，如岩盐（氯化钠）被认为是来自地下水。根据所获得的结果，厚壳…
Purpose – Salt weathering is one of the most common agents of decay of Central Asian earthen sites and is in function of water evaporation from the wall surface. Soon after excavation the earthen walls and the stupa of the Buddhist temple of Ajina Tepa (seventh-eighth century AD) started to deteriorate due lack of protection and surface erosion. The most important issue in the planning of conservation work was to understand such mechanisms and to decrease the effect of salt weathering on structural damage. The purpose of this paper is to discuss these issues. Design/methodology/approach – Evaporation distribution and salts types were studied on selected walls. In addition, three-dimensional recording of the walls and the stupa was undertaken with digital photogrammetric methods. Findings – It was clearly found that the intensity of salt weathering in the site is high and some salts such as halite (sodium chloride) are thought to originate from groundwater. On the basis of the results obtained, thick shelt...
