%X The deformation behaviors of deep excavation and its  adverse impact on surrounding environment could be effectively controlled by reinforcement  in the passive zone  which is widely applied in actual projects. With a deep excavation for the metro station in Shanghai soft soil area as  research background, the impact  of reinforcement in passive zone on excavation-induced deformation was investigated by numerical simulations. Results showed that by   reinforcement in passive zone, the magnitude of deformations could meet  control  requirements. With the increase  of reinforced depth, deformations such as lateral wall deflection, ground settlement and bottom upheaval could be effectively controlled; but  excessive improvement on the magnitude of <i>E</i><sub>50</sub><sup>ref</sup> for reinforced soil had little impact. The effect of controlling excavation deformation by reinforcement of entire basal soil is obviously superior to that by reinforcement along the diaphragm wall under equal condition.
