- Abstract:
- In order to combine evaluation method of rock slope stability under the hydraulic pressure and the Barton-Bandis nonlinear failure criterion, two common transfer methods from Barton-Bandis criterion parameters to the Mohr-Coulomb criterion parameters were explored. Following this idea, the anti-sliding stability formula was deduced by different calculation methods. Ultimately, according to the calculation example analysis, the results show that study on the anti-sliding stability factor of rock slope by JRC-JCS model is feasible; and under the single factor influence, there is a negative correlation among anti-sliding stability factor of fissure water depth in rock slopes, slope height and plane angle. This can be respectively described by linear function and power function, and they show positive correlations among anti-sliding stability factor and JCS and JRC and φb, which can be respectively described by Logarithm and exponential equation;as to fissure water depth, the influence that casts upon equivalents of c, φ is opponent,but the relationship between them also can be fitted by linear function, and the relationships between critical fissure water depth and JCS, JRC are respectively fitted by logarithmic and exponential.
