Abstract Temporal variation of rock mass properties, especially the strength degradation due to drying-wetting cycles as well as the acidic wetting fluid (rainfall or reservoir water) is crucial to stability of reservoir rock slopes. Based on a series of drying-wetting cycling and experiments considering the influences of pH values, the degradation degree models of the reduced cohesion c′, friction angle φ′ are developed.
2D stability analysis of the slope is subsequently carried out to calculate the factor of
safety (Fs) via limit equilibrium method (LEM) and a predictive model of Fs is built
using multivariate adaptive regression splines (MARS), revealing the… More >
