(This paper discusses the construction disturbance to the soil in the tunnel tunnel excavation in the urban subway section and the mechanics mechanism that causes the stratum movement and the surface deformation and settlement, and summarizes the dominant factors of the construction disturbance. Combined with the engineering practice of Shanghai Metro Line, the artificial intelligence neural network technology is used to predict the surface subsidence, and the feasibility and applicability of the above-mentioned soft science method are proved by comparison with the field measured value.)
