Abstract EN
During the shield construction of Harbin Subway Line No.
3 Project, the average ground settlement exceeds the warning value.
In order to find the cause of settlement and improve it, this paper establishes a settlement prediction model to analyse the potential influencing factors based on the Deep Belief Network (DBN) and calculated the correlation degree between influencing factors and settlement through sensitivity analysis.
It was found that the permeability coefficients of layer and cutter head torque are the main factors affecting settlement.
Then, corresponding muck improvement measures were made according to the analysis of the layer conditions, which successfully reduced the permeability and shear strength of the muck, thereby controlling the surface settlement value within the warning range.
The research results in this paper illustrate the applicability and robustness of DBN in tunnel engineering, and the related research ideas can be applied to other projects.
