Abstract

The top-down construction method of pressured grout prestressed anti-floating anchor used in Taiyuan Wanda Plaza was introduced.This kind of anchor posesses of good durability when beared compression so that the anchor fixed length was not easy to crack.In the meanwhile, the flexible arrangements and high anchoring efficiency were good for the even stress of foundation plate.In this project, the influnce of confined water was successfully removed by driving steel pipes into the layer, with which the abundant confined water was cut off and running sand was separated.Several kinds of measures were taken to prevent ground water from leaking into the basement and it was proved to be in good effect.At the same time, top-dowm construction method of anti-floating anchor was discussed.
