【摘要】：GPS定位技术具有诸多优点能够满足现代变形监测的需求。变形预测是一个影响因素很复杂的过程,灰色系统对于建模数据量要求比较低,能够有效克服回归分析等统计分析方法的不足,非常适合小样本的短期预测。以"川气东送管道南京扬子石化末站监测项目"中场地形变观测为例,简述GPS及灰色GM(1,1)模型在具体工程项目上的应用,且达到了满意的效果。
[Abstract]:GPS positioning technology has many advantages to meet the needs of modern deformation monitoring. Deformation prediction is a complicated process of influencing factors. Grey system has a low requirement for modeling data, which can effectively overcome the shortcomings of statistical analysis methods such as regression analysis, and is very suitable for short-term prediction of small samples. Taking the site deformation observation in the "Monitoring Project of Nanjing Yangzi Petrochemical Terminal Station" as an example, the application of GPS and grey GMGM1 / 1) model in concrete engineering projects is briefly described, and the satisfactory results are achieved.
