SYSTEM FAILURE PROBABILITY ANALYSIS OF COHESIVE SLOPE CONSIDERING THE SPATIAL VARIABILITY OF UNDRAINED SHEAR STRENGTH

A system failure probability analysis method of cohesive slope considering the spatial variability of undrained shear strength is proposed.In this method, the local averaging parameter of the random field of undrained shear strength on slip surface is introduced as an equivalent parameter.The statistical characters of the equivalent parameter and t

Despite the abundance of shale-oil and tight-oil reserves in the Fengcheng Formation within the Mahu Sag, exploration and development efforts for both types of reservoir are still in their early stages.A comprehensive examination and comparison of the pore structures of these reservoirs can establish rational classification and evaluation criteria.
