Method and apparatus for controlling stratum deformation in shield construction process, and non-volatile storage medium

A method for controlling stratum deformation in a shield construction process, comprising:

• monitoring settlement characteristic parameters in a shield construction process;
• predicting a settlement proportion according to the settlement characteristic parameters, the settlement proportion being a ratio between a predicted settlement value and a corresponding settlement threshold;
• and
• determining construction parameters in the shield construction process according to the settlement proportion;
• wherein the stratum deformation process in the shield construction process is divided into five settlement stages, namely a pre-deformation stage, an excavation face deformation stage, a deformation stage in passing process, a shield tail rear deformation stage, and a post-deformation stage;
• and determining construction parameters in the shield construction process according to the settlement proportion comprises:
• determining the construction parameters corresponding to the settlement stages according to a settlement proportion of each settlement stage;
• wherein determining the construction parameters corresponding to the settlement stages according to a settlement proportion of each settlement stage comprises:
• determining whether the settlement proportion of each settlement stage is within a corresponding predetermined range;
• and adjusting the construction parameters corresponding to target settlement stage when the settlement proportion of the target settlement stage is not within the corresponding predetermined range;
• wherein the construction parameters corresponding to the pre-deformation stage and the excavation face deformation stage comprise a slurry pressure, the settlement proportion corresponding to the pre-deformation stage is a first settlement proportion, the settlement proportion corresponding to the excavation face deformation stage is a second settlement proportion, the predetermined ranges corresponding to the pre-deformation stage and the excavation face deformation stage are a first predetermined range, a minimum value of the first predetermined range is a first threshold, and a maximum value of the first predetermined range is a second threshold;
• and adjusting the construction parameters corresponding to target settlement stage when the settlement proportion of the target settlement stage is not within the corresponding predetermined range comprises:
• reducing the slurry pressure when the first settlement proportion and/or the second settlement proportion are smaller than the first threshold;
• and increasing the slurry pressure when the first settlement proportion and/or the second settlement proportion are greater than the second threshold.
