Three-Dimensional Performance of an Ultra-Deep Circular Shaft in Soft Clay: Equivalent Structural Stiffness Degradation and Adjacent Structure Interaction

Ultra-deep circular shafts are increasingly deployed in congested urban environments, yet their structural performance in highly sensitive soft clay remains susceptible to diaphragm wall panel joints, structural imperfections, and complex interactions with adjacent structures. This study presents a high-fidelity three-...
