The Influence Of The Lvyin Road Excavation On The Surrounding Environment

The deep excavation engineering has been hot research field in the geotechnical engineering,and the in supporting and retaining structure of the underground continuous wall as a kind of economical and practical retaining technology is widely used in deep excavation of subway.However, Due to the surrounding environment of the deep excavation is complex. The safety accidents frequently happen. It is great significance that the study of the impact of excavation on the surrounding environment.In this paper, With using the numerical simulation buliding the 3D model of the foundation pit and the surrounding environment of Lvyin road.Studing on the effect of excavation on surrounding pipelines, buildings, and the influencing factors.The results of the measured data were compared.Through analysising the foundation pit excavation of the influencing factors on surrounding pipelines, buildings.And discussesing the factors from different distance to the foundation pit of pipeline, the different support stiffness, the different support pre axial force on the pipeline deformation, and the building damage grade evaluation.
