PDF Evaluation of minimum factor of safety in slope stability
The calculation of slope stability safety factors is a routine practice. In general it involves two steps: First, calculate the factor of safety for a specified slip surface using the method of slices. Extensive studies have been under- taken in this area, and a variety of these methods are available for generalized slip surfaces.

The distribution characteristics of brittle minerals in the Lower
The traditional experimental method for the quantitative analysis of rock microstructures is mainly focused on pore morphology. For instance, the pore size distribution method and mercury injection method are based on the idealised model relationship to reflect the complex pore system, and the rock matrix is modified to a certain extent (Wang et al., ; Li et al., 2018a, 2018b).

2011. 3. 10. · The distance between the two equipotential li nes on the downstream end in the X area is 3.3 m. The exit gradient is then computed as 0.62 divided by 3.3 making the upward gradient 0.19. Of significance for later discussions is that the gradie nt is computed for a head loss over a fairly long distance of 3.3 m.
Analysis of rock slope stability under rainfall conditions
Dec 01, · This study provided a feasible approach for more accurate analysis of rock slope stability under rainfall infiltration. To quantitatively analyse the influence of rainfall on slope stability, we attributed the influence of rainfall on slope stability to the change in pore pressure and the decrease in rock strength due to the effects of water-induced weakening.
