Due to the dense construction of underground projects in urban areas, nearby activities like foundation pit excavation can cause subsidence in the shield tunnel, posing a safety risk to subway operations. This paper proposes an optimization method using combination weighting and grey correlation degree for the Xi’an under highway tunnel project. It conducts numerical simulations of the original scheme using ABAQUS and selects calculation parameters, then optimizes anti-floating structure parameters through orthogonal experiments. The optimized operating conditions were compared with the original ones to validate the optimization results. These findings serve as valuable references for tackling real-world engineering challenges.
