Abstract: In order to achieve the goal of a safe, economical and simplicity during the construction in the deep excavation design, this paper discusses several improper designs of the supporting structure connection details. The optimized connections are proposed based on the structural analysis. The improved connection not only reduces the complexity as well as the potential risks in the construction but also result in a cost saving in the materials.
