Abstract： Desication cracking is a typical deterioration in archeological sites in wet environments. To explore thecorrelation between the development degree ofdesiccation crackingand soil properties in the Sanxingdui sacrificearcheology site，we conduct soil property analysisand quantitative characterization of deterioration， adopt the Grey Relation Analysis （GRA）to calculate the correlation degree between the six relevant indicators of soil properties and the development degree and damage degree of desiccation cracking.This research aims to study the magnitude and mechanism of each indicator's influence on the deterioration degree，and explore the feasibilityof preventing and controling deterioration by intervening in soil properties.The result shows that the corelation degree between soil properties and the desiccation cracking degr in descending order is as follows： clay particle content > clay mineral content > plasticity index > initial dry density > initial moisture content and organic matter content.The clay particle content，clay mineral content，and plasticity index are control indexes affecting the development of desiccation cracking，showing a positive correlation with it.The initial dry density，initial moisture content，and organic matter content are relevant indices，the smaller the initial dry density the more considerable the damage degree of desiccation cracking.Intervening in soil properties can only control the developmentof desiccation cracking to a certain extent; for example，increasing the initialdry density can change the morphology of desiccation cracking.

自2019年底以来，对三星堆遗址祭祀区开展了新一轮考古发掘，出土了大量精美的青铜器、象牙、金器、玉器等文物，揭露了6座祭祀坑（K3～K8）以及沟槽、小型圆形坑、房址等祭祀活动遗迹，引起了学界和社会的高度关注[1。（剩余17402字）
