The shield tunneling method is widely favored in metro construction due to its high efficiency, safety, low cost, and minimal ground disturbance. During excavation, the shield machine applies support force to the excavation face, which can disturb the surrounding soil. Excessive support force may lead to instability at the excavation face, risking damage to nearby structures and impacting construction schedules.
