Several characteristics of deformation of a rock slope due to excavation are clarified through a displacement measurement on Ikura limestone quarry for more than ten years. However, some causes of measured deformation have been still unknown. The rock slope behind the Tarumi face showed continuous contraction while the excavation was interrupted at this face. In this study, a cause of the continuous deformation was studied to evaluate stability of the rock slope by means of numerical analysis. Complex topography of the mining area on Ikura limestone quarry was modeled in three dimensions at several excavation stages. Then, an elastic analysis was carried out to estimate the deformation of the rock slope due to excavation in the whole mining area. Through the analysis, it was found that the rock slope could deform elastically while the excavation was interrupted at the Tarumi face. It was estimated to contract gradually due to progressive excavation at the Kawamukai face, which was located at 400m away from the rock slope. Analyzed results were consistent with the observed results under an adequate elastic constant. Therefore, this rock slope was evaluated to be stable because the continuous deformation caused by the excavation was elastic.
