Research on Deformation Prediction of Metro Foundation Pit based on GM(1,1)Model
In the process of excavation of deep foundation pit,the soil around the foundation pit will be disturbed,which will inevitably affect the stability and safety of the foundation pit,the buildings and structures around the foundation pit.In order to solve the problems such as too long monitoring period for long-term monitoring and monitoring data error during excavation of foundation pit,the surface settlement deformation around the foundation pit was monitored based on a project example,and the GM(1,1)prediction model was established based on the surface settlement monitoring data to predict and analyze the late settlement deformation of foundation pit.The results show that the prediction results of this model can well reflect the settlement and deformation of foundation pit,the prediction accuracy can meet the engineering needs,and the prediction results are ahead of the actual observed values,which can provide reference for similar engineering construction.
