... Abstract The deformation of the reservoir landslide is mainly governed by the combined action of rainfall and the fluctuation of the reservoir water level. The determination of the threshold of triggering factors is of great significant in the stability analysis and evaluation of the potential...

... Abstract Study the damage threshold of siltstone, we conducted the large-diameter series of split Hopkinson pressure bar cyclic impact tests on siltstone samples. When the damage value of siltstone was 0.16-0.4, increased exponentially with an increase in stress wave amplitude. Damage...

... Abstract The original rock quality designation ( RQD ) index has several limitations, such as one-dimensional (1D) direction and a single threshold. For these reasons, a novel RQD calculation method is proposed by using 3D discontinuity network simulation. In this method, a 3D discontinuity...

... that the spalling strength in low-porosity rocks can be associated with the initiation of internal cracks in the sample. However, very limited studies are available that looks at the effect of all the principal stresses on rock crack initiation stress threshold. This paper investigates the previously ignored effect...
