Numerical Simulation Analysis of Cutter Head of Large Diameter Metro Shield with Soft Upper and Hard Bottom

Abstract: Taking the large-diameter shield cutter head between Xinglong Station and Tianfu new station in Civil Engineering Section 4 of Chengdu metro line 18 as an example, the numerical simulation is carried out by finite element software to analyze the stress and deformation of large-diameter shield cutter head under different loads in upper soft and lower hard strata. The results show that the stress and deformation of cutter head meet the design requirements, which can provide certain reference value for similar pr… Show more
