大坝沉降的高精度预测对水库正常运行起着重要作用。利用灰色模型与时间序列对大坝沉降监测点的沉降进行预测,并与实测数据进行比较分析。结果表明,基于时间序列模型的预测精度优于灰色模型,更适用于实际应用,较好地描述了沉降监测点的变化规律。
The high accuracy prediction of dam settlement plays an important role in the normal operation of the reservoir. The gray model and time series are used to predict the settlement of dam settlement monitoring points and compared with the measured data. The results show that the prediction accuracy based on the time series model is better than the gray model, which is more suitable for practical application and better describes the variation rule of settlement monitoring points.
