【摘要】 通过对模型试验中竖井沉降测量数据进行一定的处理，按最佳维数建立等维新息模型-GM（1，1）模型时沉降进行预测，预测值与试验值吻合较好．建议将此法应用到实际工程中，以期能指导施工，确保竖井的稳定．更多还原

【Abstract】 In this paper,based on the proceeding of the data about the settlement of the shaft in the model experiment, the Grey Model is presented. We also suggest using GM(1,1) model to predict the settlement in the future. The prediction data are in well accord with the observing data.更多还原
