Abstract: This paper proposes a multi-construction parameter shield construction attitude prediction method based on machine learning, analyzes the construction parameters of shield tunneling in complex environment, analyzes the internal relationship between tunneling parameters and shield attitude, and establishes the predicted shield attitude. The prediction model realizes the deviation calculation between the center coordinates of the shield head and the design axis. Combined with a subway construction section, the prediction model is verified.

Key words: shield construction, tunneling parameters, machine learning, shield attitude, prediction model
