Abstract: The Qingtian Exhibition Center resettlement housing project is located in downtown Qingtian. The proposed site is occupied by a movie theater surrounded by the residential buildings and is not favorable for the deep excavation. Considering the poor conditions of engineering geology as well as poor hydrogeology, a careful design for the deep excavation supporting structures is required in order to ensure the safety, reliability and cost effectiveness during the construction. The stability of the deep excavation process was analyzed by commercial excavation software.

Key words: Deep Excavation, Excavation Support Structures, Excavation Design
