摘要：
According to the results of creep testing on the sandy mudstone at Beishan open pit coal mine in Xinjiang, the creep curves were described by the visco-elastoplastic creep model and the time-varying parameters were revealed via Hoek-Brown strength criterion. The dynamic stability of the slope was analyzed using FLAC3D numerical software. The result shows that the slope safety factor is reduced to 1.15 from 1.59 after 18 years, which is lower than the specification requirements. This work provides a theoretical basis for the assessment of the dynamic safety of this slope during its service life.
