Stability analysis of a high and steep rocky slope based on preferred plane theory

Preferred plane theory and its importance is briefly introduced here,and it is applied to the stability analysis of a high and steep rocky slope. Based on the related geological data,the planes which hold advantage in each evaluation metric are determined. By analyzing the influence degree of the preferred planes to slope stability with the stereographic projection,stability-controlling preferred plane combination is obtained and is taken into account in the calculation-analysis model of rock ma...
