Three-parameter strength reduction method for slope stability evaluation
Disclosed is a three-parameter strength reduction method for slope stability evaluation. The present disclosure reflects the difference in the attenuation and contribution of the cohesion, internal friction angle and tensile strength in the process of slope instability by reducing the three parameters by different reduction factors. Based on the sudden change of the characteristic point displacement of the slope as a criterion of slope instability, the present disclosure derives the fitting relationship between the characteristic point displacement and the cohesion reduction factor. The present disclosure assumes that the comprehensive safety factor satisfies a linear relationship with the cohesion reduction factor, the internal friction angle reduction factor and the tensile strength reduction factor and derives the relationship between the comprehensive safety factor and the cohesion reduction factor. Finally, the present disclosure summarizes and proposes a three-parameter strength reduction method and provides the steps for analyzing the slope stability through this method.
