Abstract: The ground anchors combined with the piles are widely used in the deep excavation projects. The horizontal deformation of the excavated wall can be reduced if the pre-stressing is applied on the ground anchors. The number of the ground anchors and their locations can be flexibly arranged according to the deformation control requirements. The other advantage of the use of ground anchors is that the internal strutting support numbers can be reduced and working spacing inside the excavated area so that the excavation as well as the foundation construction work can be facilitated. This paper presents the design and analysis aspects of the ground anchor applications in supporting of the deep excavations of the MultiPurpose Building of the Patient Center for Chinese Medicine Hospital of Jinhu County.
