Claim 4:
5. The method according to claim 1, wherein the construction parameters corresponding to the deformation stage in passing process comprise at least one of a fluctuation value of a incision water pressure, a tunneling speed, a cutter head torque, a cutter head rotating speed, and a filling material injection rate, the settlement proportion corresponding to the deformation stage in passing process is a third settlement proportion, the predetermined range corresponding to the deformation stage in passing process is a second predetermined range, a minimum value of the second predetermined range is a third threshold, and a maximum value of the second predetermined range is a fourth 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:
increasing at least one of the fluctuation value of the incision water pressure, the tunneling speed, the cutter head torque, and the cutter head rotating speed, and/or reducing the filling material injection rate when the third settlement proportion is smaller than the third threshold; and
reducing at least one of the fluctuation value of the incision water pressure, the tunneling speed, the cutter head torque, and the cutter head rotating speed, and/or increasing the filling material injection rate when the third settlement proportion is greater than the fourth threshold.
