摘　　要：为保证工程建筑物施工和运营期间的安全稳定,必须对其进行变形监测。笔者采用灰色系统理论,建立GM(1,1)基坑变形预测模型,并利用北京中国尊基坑工程的实际监测数据对基坑钢筋应力变形值进行预测。结果表明,模型残差<0.7 kN,预测值与实测值吻合度较好,证明该预测模型具有较好的精度。To ensure the safety and stability during the building construction and operation,deformation monitoring must be carried out.The GM(1,1)pit deformation prediction model is designed based on the gray system theory,and the actual monitoring data from Beijing foundation pit project of China Zun is used to predict stress deformation values of pit reinforcement.The results show that the new model residual is less than 0.7 kN and the predicted values are in good agreement with the actual measurements,proving that the prediction model has better precision.
