Abstract

Stress and strain characteristics of rock and earth mass in a slope under the condition of underground mining.

Author(s): L.V.Yi-qing

As a typical example, Fengmaoding slope located in Gujiao, Taiyuan, was selected to analyze the stress and strain characteristics under the condition of underground mining, in mountain area. Geologic model was constructed based on the true data from Fengmaoding slope. Combined with the deformation mode of slope under the condition of exploit, numerical model was set up. And the stress and strain changes in the slope was simulated under the condition of underground mining. According to the simulation, failure deformation process was gotten. As a result, the main factors influencing the stability of the slope are the goaf underground and the faults in the slope.
