Research on a Non-Synchronous Coordinated Reduction Method for Slopes Based on the Hoek–Brown Criterion and Acoustic Testing Technology

Li He,

et al.

Abstract: In the process of the evolution of rocky slope instability, the decay deterioration rate of cohesion c and internal friction angle φ are different, and there are also differences in the order and degree of their impact on slope stability; thus, it is of great theoretical value to propose a more practical calculation method for the reduction in slope degradation. This paper combines the Hoek–Brown criterion and an acoustic test method to estimate the mechanical parameters of slope rock mass; the correlative rel… Show more

“…So far, many researchers have attempted to analyze slope stability under the action of blasting disturbance through finite element numerical analysis method based on the limit equilibrium theory, and achieved certain research results [13][14][15]. While exploring the stability of rock slopes based on the limit equilibrium theory, relevant researchers consider blasting disturbance load from three perspectives: (1) Apply equivalent blasting disturbance load to the slope surface based on relevant equivalence principles [16,17]; (2) Establishing key equations for blasting disturbance based on experience in blasting vibration engineering and incorporating limit equilibrium theory [18,19]; (3) According to blasting vibration engineering experience, the strength of relevant parameters of slope rock mass is reduced to simulate the influence of blasting vibration load on the mass of slope rock, among which the second one has gradually become a mainstream method [5,[20][21][22]. The research on discrete element analysis is mainly based on the implicit solution in the system, and slope stability under the action of blasting disturbance is analyzed by establishing an explicit equation of blasting load [23,24].…”
