Description
Summary:This study focuses on investigating the rheological properties of the rock mass surrounding STA134 underground decline at PT XYZ. The research utilizes tunnel displacement monitoring data and employs regression and numerical methods for data analysis. The findings reveal that the Burger Rheology Model serves as an appropriate rheological model for this study. The regression method yields higher results for rheological parameters compared to the numerical method. The rheological parameter values obtained through regression are as follows: ?2 = 364.28 GPa days, ?1 = 23.37 GPa days, and G1 = 261.70 MPa. Meanwhile, the numerical method yields rheological values for the rock masses as follows: ?2 = 250 GPa days, ?1 = 20 GPa days, and G1 = 200 MPa.
