Claim 6:
7. He method according to claim 1, wherein the construction parameters corresponding to the shield tail rear deformation stage comprise a grouting pressure and/or a grouting amount, the settlement proportion corresponding to the shield tail rear deformation stage is a fourth settlement proportion, the predetermined range corresponding to the shield tail rear deformation stage is a third predetermined range, a minimum value of the third predetermined range is a fifth threshold, and a maximum value of the third predetermined range is a sixth 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 grouting pressure and/or the grouting amount when the fourth settlement proportion is smaller than the fifth threshold; and
increasing the grouting pressure and/or the grouting amount when the fourth settlement proportion is greater than the sixth threshold.
