摘　　要：深基坑的变形及其预测是工程建设中经常遇到的重要问题,论文对加权灰色模型应用于该领域作了探讨。在进行加权模型理论计算的基础上,以深基坑实际变形监测资料为基础,利用原始模型结果作为比较基础,对加权模型进行了变形预测计算。对比结果表明,时距权重模型的原点误差相对于原始模型大为减少,模型的预测精度也得到了很大的提高,加权模型可以很好的应用于基坑变形的预测与分析。Deformation predication in deep construction pit is the common problem in engineering Construction, especially in the high and superhigh building construction. In this paper, weighted grey model was discussed. The weighted grey model was theorially described firstly and then deformation data from certain deep construction pit were used to be predicted by weighted grey model on the basis of original model. The results show that the errOor at original point is much more largely reduced in time-distance weighted model than original grey model and the predicttion accurracy increases, too. Therefore, the weighted model can be used in pit deformation prediction.
