Grey Correlation Analysis of Factors Influencing the Stability of Loess Strata in Shield Tunneling
In the context of shield tunneling through loess strata, this study utilizes a refined simulation model in FLAC3D to calculate a total of 30 parameters associated with five factors influencing the maximum displacement of the surrounding rock. Through grey correlation analysis, the impact of each factor on tunnel stability is assessed. The results indicate that the maximum displacement of the surrounding rock exhibits a decreasing trend with an increase in the silo pressure, grouting material strength, and soil deformability, while it shows an increasing trend with greater tunnel depth and soil density. Both tunnel depth and soil density exhibit grey correlation coefficients exceeding 0.9, establishing them as the predominant factors influencing tunnel stability. Silo pressure, grouting material strength, and soil deformability all demonstrate grey correlation coefficients of approximately 0.5, designating them as secondary factors in this analysis.
