Abstract: Some parameters in the design of multipropped deep foundation pit are analyzed; and the selection of flexibility parameters of prop and retaining wall is compared. Using FEM, an orthogonal design test of the excavation of deep foundation pit is carried out considering 4 levels of the prop stiffness, displacement flexibility number; elasticity modulus and so on, and the influences of these parameters on the excavation deformation are obtained. It is concluded that the displacement flexibility number of retaining wall is primary parameter which controls the deformation of foundation pit; other parameters, such as stiffness of soil, etc., have little influence on deformation of deep excavation.

Key words: multipropped excavation, orthogonal design, displacement flexibility number, finite element modeling
