摘要
针对基坑变形系统的不确定性及灰色性,结合工程实例,采用自适应GM(1,1)模型对基坑监测数据进行了变形预测,结果表明采用自适应模型大大提高了长时间段预测精度,预测结果完全满足工程要求,具有较好的实用价值。
Aiming at the uncertainty and gray of foundation deformation system, combined with engineering examples, the foundation monitoring data was deformation forecasted with self adaptive GM （ 1, 1 ） model. The results indicated that self adaptive model enhanced greatly long time forecasting precision, the forecasting result satisfied completely engineering requirement and had better use value.
