Abstract: Through calculation software and finite element calculation, combining with engineering examples, the influence of dewatering ouside excavation on deformation, stress state and surrounding ground settlement of diffirent types of deep foundation pit were researched. Then, some conclusions were drawn, which provide references and suggestions on the application of dewatering ouside excavation to deep foundation pit.
Keywords: dewatering outside excavation; deformation; stress state; surrounding ground settlement; optimal dewatering level; finite element
