为了对基坑的早期竖向位移值进行预测,根据某基坑的早期竖向位移沉降值作为样本数据,结合拟合法以及灰色理论两种预测方法对其进行预测,并将预测结果进行对比。计算结果说明在不同的样本数下运用两种预测方法对基坑的早期竖向位移值进行预测均是可行的,运用拟合法进行基坑的早期竖向位移值的预测更为准确。所得结果可为基坑监测以及施工提供参考。
In order to predict the early vertical displacement of foundation pit, according to the settlement value of early vertical displacement of a foundation pit as a sample data, the prediction method is combined with the two prediction methods of fitting method and gray theory, and the prediction results are compared. The calculation results show that it is feasible to predict the vertical displacement of the foundation pit by two kinds of prediction methods under different sample numbers. It is more accurate to use the fitting method to predict the vertical displacement value of the foundation pit in the early stage. The results can provide reference for foundation pit monitoring and construction.
