According to failure mode and rheological properties of surrounding rock under excavation unloading, the characteristics of loading failure, creep effect and unloading mechanism were summarized and induced by Li et al. (2012). Based...

... Abstract True triaxial tests have been carried out on two porous sandstones, Coconino ( n =17.5%) and Bentheim ( n =24%) to investigate the effect of the intermediate principal stress (σ 2 ) on compressive strength, failure-plane angle and failure mode. These rocks were selected because...

... and failure modes of open pit slope containing faults and achieved satisfying results. Based on weakening method and interface method, numerical simulation was used on the stability analysis of slope containing a downslope fault (Wang Xinyu et al., 2011). The dynamic response of rock slope of Huangmailing...
