摘要
云冈石窟盐害机理研究对于治理策略选择具有重要意义,为探析云冈石窟风化砂岩破坏形式与岩面伴生盐类析出物的关系,本工作采用XRD法进行了矿物组成的半定量测试,采用酸碱中和法进行了CO_(2)含量测定,另外采用XRD进行了盐类矿物和硅酸盐矿物定性鉴定,试图探析云冈石窟风化砂岩破坏形式与岩面伴生盐类析出物的关系。结果显示:云冈石窟岩面片状风化与砂岩碳酸盐含量高有关,而粉状风化与岩石中石膏含量高有关,不同盐类结晶析出与洞窟环境有关,这些研究结果对云冈石窟风化病害治理有借鉴意义。
Research on the mechanism of salt damage in Yungang Grottoes is of great significance to the selection of treatment strategies.In this paper,X-ray diffraction(XRD)was used to conduct semi-quantitative analysis of mineral composition and the acid-base neutralization method was used to determine CO_(2) content,XRD was also used to conduct qualitative identification of salt minerals and silicate minerals,in an attempt to analyze damage patterns in weathered sandstone in Yungang Grottoes.The relationship with the salt precipitates associated with the rock surface.The results suggest that the flaky weathering of the rock face at Yungang Grottoes is related to the high carbonate content of the sandstone,and the powdery weathering is related to the high content of gypsum in the rock.The crystallization of different salts is related to the cave environment.These research results have reference significance for the treatment of weathering diseases in Yungang Grottoes.
