摘要
文中简要介绍了灰色系统理论,针对西安市单个水准点的一组高程时间序列观测数据,建立了灰色预报GM(1,1)模型,预测西安市某点近期沉降量。计算结果表明,预测模型计算结果与实测值拟合较好。同时,用VB编制了灰色模型预测程序,证明其正确性和有效性,并绘制了其高程沉降图。
This paper has a brief introduction on the gray system theory,and establishes the gray predicting GM(1,1) model by using a column of time series observation data of a single bench mark in Xi'an. Then it predicts the recent surface subsidence in Xi'an by this model. The findings show the forecasting result of gray model is in a coincidence with the actual results. At the same time,the gray model predicting program is written by VB to prove its validity and effectiveness through experiments,and drawing up the height fallout plot by computer.
