灰色系统理论在变形观测中的应用

Application of Grey Forecasting Model in Monitoring Deformation of Deep Excavation

建筑施工中,沉降监测是监测建筑物是否安全的重要环节,将灰色系统理论应用于建筑物沉降变形的数据分析,结合沉降观测实例,可进行沉降预测结果的分析和检验,进而证实建筑物沉降变形分析中采用灰色GM(1,1)预测方法的可行性,

Based on literature review and discussion about the concept of “Grain for Green” program, the necessity and the urgency to evaluate the ecological benefits of the project were analyzed, and the present status and the research methodology for evaluation on ecological benefits produced by the program of “Grain for Green” both at home and abroad were elaborated. The problems occurred in the benefit evaluation on the program were analyzed, and the relevant development tendency was discussed.
