%X The deformation and strength characters are the most concerned indicators in the field of geotechnical engineering and engineering mechanics. On the basis of laboratory test and in consideration of geostress, size, direction and connectivity of structural plane, the macro-mechanics parameters of rock slope are obtained by optimization back analysis using dividing and grading method. The results are applied to three-dimensional finite element calculations. Calculation result suggests that the macro-mechanics parameters objectively and reasonably reflect the safety and stability of the slope. This research provides a reference for the back analysis and slope stability research.
