Abstract
An anchored band bracing system was introduced for the bracing of a deep excavation in hard clay with low-level expansion. In this system, stress redistribution was considered to further deduce the thickness of the surfacing shotcrete, global stability was ensured by prestressed anchors and a concrete band for the distribution of the prestress. The bracing system was shown to be cost effective and reliable under certain conditions, it is the first project using prestressed anchors combined with shotcrete for deep excavation bracing in hard clay with low level expansion in P.R. China. In this paper, the design procedure and criteria for both surfacing and global stability were summarized.

An Anchored Band Bracing System for Deep Excavations in Clay
St. Louis, Missouri
An anchored band bracing system was introduced for the bracing of a deep excavation in hard clay with low-level expansion. In this system, stress redistribution was considered to further deduce the thickness of the surfacing shotcrete, global stability was ensured by prestressed anchors and a concrete band for the distribution of the prestress. The bracing system was shown to be cost effective and reliable under certain conditions, it is the first project using prestressed anchors combined with shotcrete for deep excavation bracing in hard clay with low level expansion in P.R.
