【Abstract】 A nonlinear finite element analysis is presented to study the effects of the structural parameter of the prestressed anchor flexible retaining.Attentions are paid to the problems,such as different anchor length,anchor space,shoring obliquity and surface thickness.The effects of these factors on the deflection of excavation and internal force of anchor are considered.The mechanics of the anchor support is indicated more deeply.At the same time the results of the paper provide the references to designing for actual engineering.更多还原
