Abstract
The earthen ruins are precious historical imprints left over from ancient human life and production, and have important cultural values. Chinese ancient ruins are widely distributed, large in number, and numerous in types. Most of the unearthed ruins are large in scale, immovable, and closely related to the surrounding environment. This paper takes the Shenna ruins as the research object, realizes the investigation of the occurrence environment of the ruins through geotechnical survey technology, and explores the reasons for the deterioration of the soil at the ruins of Shenna through the research of the correlation between the occurrence environment and typical diseases. On the basis of traditional cultural relics survey, the geological, environmental characteristics and geotechnical engineering conditions of the ruins were identified, analyzed, and evaluated through survey methods. Combined with indoor experimental analysis, it was found that the main reason for the deterioration of Shenna ruins was the migration of water and salt in the soil caused by seasonal precipitation, and combined with the geotechnical investigation results, the possibility of groundwater damage in this area is eliminated, which provides a research basis for the preventive treatment of water environment in the future protection and restoration of the Shenna ruins, and provided very useful technical application reference and research idea for such earthen ruins protection in Northwest China.
