Research on Prediction of EPB Shield Tunneling Parameters Based on LGBM
BuildingsAt present, the determination of tunnel parameters mainly rely on engineering experience and human judgment, which leads to the subjective decision of parameters and an increased construction risk. Machine learning algorithms could provide an objective theoretical basis for tunnel parameter decision making.
