Desiccation cracking is a typical deterioration in archeological excavation sites in a wet environment. To explore the correlation between the development degree of desiccation cracking and the soil properties in the Sanxingdui archeological site, the Grey Relation Analysis (GRA) is separately adopted to calculate the correlation degree between the selected six soil properties and the desiccation cracking development degree and the damage degree of fissures to the soil. This research aims to study the influence of each soil property on the development degree and to explore the feasibility of deterioration prevention and control by soil properties intervention. The result shows that the correlation degree of soil property and desiccation cracking development in descending order is as follows: the clay particle content > the clay mineral content > the plasticity index > the raw dry density > the raw moisture content, and organic content. The clay particle content, clay mineral content, and plasticity index are control indexes affecting the development of desiccation cracking, which show a positive correlation. While the raw dry density, raw moisture content, and organic content are relevant indices, in which the value of dry density is smaller, the damage degree of desiccation cracking is more serious. The soil properties intervention influences the desiccation cracking development degree to some extent, in the later practice reducing desiccation cracking by increasing dry density can be considered.
