摘要：

金茂大厦地下结构支护方案之一是采用地锚作为地下连续墙的锚固结构,为了确定设计参数,验证地锚施工的可行性,开展了一系列科学研究,通过直锚和斜锚的施工工艺现场试验,达到了预期效果。抗拔力达到了设计初定的300t指标要求,为地锚设计与施工提供了依据。

One of the proposed shoring systems for the underground structures of Jinmao Mansion was to use ground Anchors as the anchoring structure of the underground diaphragm walls.To decide the design parameters and verify the feasibility of construction of ground anchors,a series of scientific researches were made and field tests of the technological process for construction of vertical and raking ground anchors were made.Through the tests,expected results have been achieved and the pullout capacity of the anchors reached 300 t as preliminarily intended by designers,providing basis for the design and construction of the ground anchors.
