Research on Deformation Prediction Based on GM(1,1)Model

变形监测是大型建筑物、构筑物安全运营的保障性工作,而要避免灾害的发生,则需要进行相应的预测预警。从变形监测理论出发,探讨了当前变形预测的模型,开发了基于MATLAB的GM(1,1)模型计算程序,结合某沉降变形监测数据进行了预测分析,给出了预测精度评价和对比图,对GM(1,1)模型在变形预测中的应用是一次很好的实践。

The deformation monitoring is the protection work of large buildings＇ and structures＇ safe operation,and in order to avoid disasters,people need to make the appropriate forecasting and early warning.Starting from the deformation monitoring theory,this paper discusses the current deformation prediction model,develops the calculation program of based on MATLAB＇s GM（1,1） model,and connecting with the deformation monitoring data of a sedimentation,makes the prediction analysis,and gives the prediction accuracy evaluation and comparison chart,which is a very good practice for the application of of GM（1,1） model in deformation prediction.
