The Sensitivity Analysis Of Stability Factors Of Rocky Slope With Ecological Restoration

Based on orthogonal experiment, the thickness of protection habitat base material (PHBM), the cohesion of PHBM, the internal friction angle of PHBM, the slope height, the slope angle and the density of PHBM are selected as influencing factors of stability of rocky slope with ecological restoration (RSER) and each factor is considered three levels. Then, using strength reduction FEM by the software ANSYS, the safety factor of RSER in various combinations is analyzed. Finally, range analysis and comprehensive assessment are applied to the assessment of results. It is showed that the cohesion of PHBM is the dominant sensitivity factor which affects the stability of RSER, flowing by the slope height, the slope angle, the thickness of PHBM, the internal friction angle of PHBM, the density of PHBM.
