Study on deformation characteristics of deep foundation pit in sandy cobble stratum based on discrete element method
Considering the characteristics of sand gravel the deformation characteristics of deep foundation pit in sandy cobble stratum are analyzed by numerical simulation and field measurement.The following conclusions are obtained that pile+internal support is the most commonly used retaining structure of foundation pit in sandy cobble stratum.With the excavation of the foundation pit,the maximum deformation of the retaining structure moves downward,and the maximum deformation of the retaining structure is located in the middle of the exposed retaining structure.The maximum value of surface settlement is 4～8 m away from the edge of the foundation pit,and the position of the maximum value moves outward with the excavation depth of the foundation pit.
