Prediction Method for Ground Subsidence of Foundation Pit Excavation
Wei Liu · Jisuanji gongcheng · 2010
In order to predict the surrounding ground settlement of deep foundation pit excavation accuracy,a new method GGEP(Grey Gene Expression Programming) is proposed to predict the surrounding ground settlement of deep foundation pit excavation,which combines Gene Expression Programming(GEP) with Gray Model(GM).The new model is verified by Shanghai Metro engineering.Experimental results show it is higher goodness of fit with actual monitor data than traditional method.Not only its forecasting accuracy is higher,but also it can self-study to adapt new environment.
