Abstract：
Considering that the Verhulst model has a sound basis for modeling and good prediction results for the final deformation of surrounding rocks, this paper discusses its serviceability and accuracy in the prediction of rock deformation and compares it with the traditional model. The results show that the prediction accuracy increases with a decrease of parameter a in the Verhulst model, and its variation law will contribute to the selection of the optimum time for secondary lining installation without any external disturbances.
