Shield segment floating prediction method considering influence of forming sequence

A shield segment floating prediction method considering the influence of a forming sequence belongs to the technical field of tunnel construction data analysis and new generation information, and mainly comprises four steps of constructing a shield segment forming monitoring variable space-time sample, extracting displacement and action characteristics, constructing a segment floating prediction model, and training the segment floating prediction model. The method comprises the following steps: reckoning floating deformation spatio-temporal evolution information of a previous formed segment ring influenced by stratum rock-soil mechanical properties, underground water and slurry filling quality into current assembly ring segment floating influence factors, combining tunneling parameters and displacement monitoring feature extraction, constructing an explicit segment floating prediction model, solving model parameters through self-adaptive step length parallel iteration, and predicting the segment floating of t
