摘　　要：介绍用指数平滑模型与时序分析方法对基坑的水平变形预测技术,并随着新数据的加入适时修改平滑系数预测变形值。工程实例研究表明:该方法与单独指数平滑模型相比可使预测值与实际位移值之间的误差更小,与曲线拟合技术相比更加稳定。The paper introduced the pit horizontal deformation forecasting technology, in which exponential smoothing model and time - series analysis model is adopted. With the addition of new deformation data, the smoothing coefficient is continuously modified. The result indicated that this method may cause smaller error value between forecast value and actual deformation value comparing with single [PVV] criterion, and may be more stable comparing with the curve fitting model.
