离散灰色DGM(1,1)模型在高层建筑物沉降预测中的应用

Application of Discrete Grey DGM(1,1) Model in Prediction of High-rise Building Settlement

针对高层建筑物沉降观测数据序列的特性,结合西昌市某工程沉降观测项目,重点阐述离散灰色DGM(1,1)模型原理及特性,以Matlab为仿真平台,将DGM(1,1)模型运用于高层建筑物沉降预测,并对其预测性能进行检验。结果表明,该方法能较好地模拟沉降发展趋势,且误差小,能达到精度要求,为后期工作提供数据支持。

In view of the characteristics of the observation data sequence of the settlement of the high-rise building,this paper focuses on the principle and characteristics of the discrete grey DGM （1,1） model combined with theproject of a project in Xichang, and uses the Matlab as the simulation platform to apply the DGM （1,1） model to thesettlement prediction of the high-rise building, and to test its prediction performance. The results show that themethod can better simulate the development trend of settlement, and the error is small, which can meet the accuracyrequirements and provide data support for later work.
