Test Study on the Influence of Foundation Pit Excavation on the Surface Settlement of Sandy Soil Natural Foundation of Adjacent Buildings

The excavation of a foundation pit will break the original stress balance and affect surface settlement natural adjacent buildings, so deformation control is very important. In this paper, numerical simulation results additional caused by were compared with experimental to verify accuracy model obtain reliable ratio building width average particle size sand that was not affected effect. Then, distribution variation law studied test, relationship between depth load obtained.
