摘　　要：以深基坑实际变形监测资料为基础,应用新还原预测模型对某基坑进行了变形模型的计算、精度分析与变形预测,得到了基坑变形新还原模型的形预测结果。对比新还原模型与原始模型结果表明:新还原模型的原点误差相对于原始模型大为减少,模型精度和预测精度都得到较大的提高,可用于基坑变形的预测与分析。Deformation predication on deep construction pit is studied on the The accuracy and feasibility are analyzed by using practical monitoring data. basis of new reduction model. Results demonstrate that the new reduction model achieves perfect predication and has the greater accuracy than the original model does while the original point errors are largely reduced.
