Aiming at deep roadway anchorage solids, laboratory
similar model tests were used to reveal the mechanical
properties of anchorage solids with different anchorage lengths under
the coupling effect of temperature and pressure, and SPSS statistical analysis
software was used to conduct linear regression analysis of the ultimate
anchorage force obtained from the tests. The results show that: through
multiple linear regression analysis, the influence degree of temperature and
pressure coupling on the ultimate anchorage force is arranged in order of
anchoring length > surrounding rock strength > temperature > side
pressure coefficient, and the linear regression equation of the model is
obtained. Compared with the linear regression equation of simulation results,
the model has a high explanatory ability.
