利用灰关联分析方法对降雨量、三峡库区水位、水位孔水位等影响因子进行灰关联度分析,得出了影响因子与水位孔地下水位的关联程度,根据此关系建立了MGM(1,n)模型。根据三峡库区近坝库段大坪滑坡中某一滑坡带2007年至2009年监测数据,对大坪滑坡体三个监测孔水位分别进行了预测,并对预测值进行了精度分析,得到了合理可靠的结论,为三峡库区滑坡体的稳定性预测预报提供了有益的建议。
Gray relational analysis was used to analyze the influence factors of rainfall, the water level of the Three Gorges reservoir and the water hole level in the Three Gorges Reservoir, and the correlation between the influencing factors and the groundwater level in the water hole was obtained. Based on this relationship, MGM (1, n )model. According to the monitoring data of a landslide in the Daping landslide near the dam area in the Three Gorges Reservoir from 2007 to 2009, the water level of the three monitoring holes in the Daping landslide body was predicted respectively, and the accuracy of the predicted values was analyzed. The reasonable and reliable The conclusions provide useful suggestions for the prediction and prediction of landslide stability in the Three Gorges Reservoir Area.
