基于Matlab的灰色线性回归模型在高层建筑监测中的应用

Application of Grey Combination of Regression Model Based on Matlab in High-rise Monitoring

基于线性回归模型和灰色模型,介绍灰色线性回归模型的建模方法,并通过MATLAB进行程序编写,运用于高层建筑因自重引起的沉降监测预报.通过义乌经济开发区工程实例表明,灰色线性回归模型相对于线性回归模型和灰色模型有着较高的预报精度,并且预报精度稳定,充分体现将灰色线性回归模型应用于高层建筑监测中的合理性和有效性.

Based on the linear regression model and grey model,the grey combination of regression model was introduced,and the program was written by MATLAB,which was applied to the prediction of settlement monitoring of high buildings.The engineering example in Yiwu showed that the grey combination of regression model was compared to the linear regression model and grey model had higher prediction accuracy and stable forecast accuracy. The result reflected the grey combination of regression model is proved to be reasonable and valid in high building monitoring.
