Abstract
In order to enhance forecasting precision for the vertical displacement of supporting structure,this paper proposed an improved least-squares method model.By using the modified data taken from the traditional least-squares method model,an improved least-squares method model was built based on the pre-settlement value,which ensured the original dimensionality and retained the settlement growing trend of the whole information.Taking the foundation pit supporting structure of composite steel soil-cement mixed diaphragm wall as a study project case,the improved least-squares method was used to study collected monitoring data,and the fitted curve of the displacement of the supporting structure was obtained and further obtained the fitted value.The results show that the absolute error of the improved least-squares method is smaller than that of the traditional least-squares method,and the prediction accuracy is improved.The improved least-squares method model not only ensures the original dimensionality,but also retains the growing trend of the whole information,which is more suitable for the prediction of the supporting structure with complex surrounding environment.关键词
