锚定板挡土结构是松散的柔性结构。所谓松散是指挡土板、立柱、锚定板及其间土体是互不联结的松散状态,仅靠土体的侧压力撑紧,使之成为牢靠的构筑物。所谓柔性是指拉杆富有弹性,在流限时具有伸长率及锚定板受力后的位移值均可对墙面提供位移量,从而使土压力减少,逐渐接近极限状态时的主动土压力。这种松散与柔性使结构产生较大的变形,令
Anchor plate retaining structure is a loose flexible structure. The so-called loose refers to the retaining plate, column, anchor plate and the soil between the loose state is not linked to each other, only by the lateral pressure of soil tight, making it a solid structure. The so-called flexibility refers to the flexible rod, the flow limit with the elongation and the anchor plate displacement force displacement can provide the wall, so that the earth pressure decreases, gradually approaching the limit state of active earth pressure. This loose and flexible structure to produce greater deformation, so
