Abstract: The demands for the highrise buildings and the underground spaces have been accelerated in recent years with the fast development of the urban construction. The increasing in number of deep excavation projects boosts the technology of excavation technology. Therefore, the excavation supporting technology becomes more and more important for the stability of the excavated area. Different excavation supporting systems are successfully applied in the various projects. Based on the case history of the deep excavation supporting design and construction of an ecology and technology park, this paper presents the results of supporting structure design, dewatering design and the excavation monitoring. The results indicate that the excavation was successful.
