Abstract:There are few reports of the stone wall with icy veins. In order to explore the protection method, this paper conducted a field investigation of the stone wall with icy veins in Jingfu Palace. Firstly, according to the stone wall disease survey, the color ratio of stones , disease area and other data are analyzed statistically. Secondly, combined with the results of thin section identification, X-ray diffraction, bulk density and water absorption test, the stone wall disease analysis was carried out, and the material and process of the tone wall with icy veins were discussed. This study can provide reference for subsequent protective repair projects.
