摘要
针对红山窑水利枢纽泵站地质条件的特殊性,提出在现有沉降观测数据的基础上,运用灰色理论的方法,建立GM(1,1)模型。通过数值试验确定模型最佳维数后,采取淘汰过于陈旧的数据信息、补充新观测数据的方法,即建立GM(1,1)等维新息模型,来预测该建筑物的沉降量。分析结果表明,GM(1,1)等维新息模型能较好地预测该泵站的沉降发展趋势。
Considering the particular geological condition of the Hongshanyao Pumping Station,GM(1,1) model and GM(1,1) equal dimension and new information model are established based on the existing observation data to predict the construction subsidence with the method of grey theory.The equal dimension and new information model means eliminating old data information and adding new observation data,and its dimension is decided through numerical experimentation.The analysis results show that the subsidence tendency o...
