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.
