The gray system is a mathematical method to predict the data in the state of poor data.In this pa-per,the research object is the foundation pit project of Chunhu resettlement house in Huangshi City,Hubei Province,based on which the GM(1,1)prediction model of foundation pit is built to predict distribution and the changing characteristics of crown beam settlement around it.The results show that the relative error be-tween the predicted and measured results is 1.33%～10.95%,and the relative error rate decreases with the monitoring time,which meets the requirements of the relevant specification for foundation pit monitoring and warning on construction prediction accuracy,and can be used to guide practical applications.
