Abstract: The creep parameters of rockmass are essential data of geotechnical engineering design. To accurately determine the creep mechanical parameters of rockmass, considering the advantages of the analytical inversion method and intelligent inversion method, the analytical intelligence inversion method coupling the analytical inversion and the intelligent inversion is developed. The proposed method is applied to the Dagangshan hydropower station project to obtain the compressive creep parameters of rockmass in dam zone. The results show that analytical intelligence inversion creep curves are more coincident with experimental creep curves than the analytical inversion creep curves, proving that the creep parameters obtained through the analytical intelligence inversion method to be more accurate and reliable, and hence the validity and rationality of this inversion method are also verified. The method provides an important theoretical guidance for efficient rheological parameters inversion of rockmass in dam area.

Key words: creep parameters of rockmass, analytical inversion, intelligent inversion, analytical intelligence inversion method
