Abstract: According to the details of a typical ultra-large deep excavation project, the key points in the design and construction of the semi-top-down construction method and some deformation-control measures in construction are introduced. In addition, the positions of the maximum deformation and the deformation rules are discussed according to the monitoring data. The relatated key points and the results of the design can be referred for similar projects.
