| 摘 要： | 针对非等步长数据,传统GM方法是构造等步长序列,生成1-AGO序列,再建立等步长GM(1,1)模型。考虑到变形观测序列非等步长特性,以相邻观测时间间隔为权,直接生成1-WAGO序列,建立非等步长GM(1,1)模型。将GM(1,1)模型应用于堤防工程沉降观测分析与预报,得到了有益的结论。 |
| 关 键 词： | 非等步长 GM(1,1)模型 1-WAGO 沉降监测 |

| Abstract: | For the unequal-step data,the traditional GM method is to establish the equal-step GM(1,1)model by constructing equal-step sequence and making 1-AGO sequence.Considering the unequal-step characteristic of de- formation monitoring sequence,the time interval is taken as weight and the 1-WAGO sequence directly made and the unequal-step GM(1,1)model established.The models is used to analyze and forecast the settlement ob- servation of embankment project,some useful conclusion is obtained. |
| Keywords: | unequal-step grey model(1 1) weight accumulating generation operator settlement observation |
