... Abstract The usual way to carry out rock slope stability analyses is: to make a rock mass discontinuity pole counting to identify the predominant directions of rock discontinuities; with strength data for the discontinuities, to carry on plane, wedge and toppling failure analyses...

... of the different types of rock-fall (plane-slide, toppling, wedge, …) which potentially could occur on the slopes overhanging the road and the village. Trajectories, distances and probability of rock-falls were calculated and mapped for each slope-site which displayed a high-rate in generating rock-falls...

... ABSTRACT A methodology is presented for the calculation of the load carrying capacity of a 2D symmetric roof rock wedge within a confining surrounding stress field, taking into account the progressive nature of yield on the wedge joints. A two stage joint relaxation procedure is employed...

... Abstract RMR and Q derived support measures for three tunnels were compared with those derived by rock wedge analysis. A numerical model was also run to assess the effect of internal water pressure in one of the tunnels. The study showed that although the empirical support recommendations...

... in high initial stress field are studied. Then, a model of reliability analysis based on shear sliding wedge theory is found. Finally, Rosenblueth's method is used to determine the reliability of stability of sliding wedges and some important conclusions are obtained. I. INTRODUCTION Jinchuan nickel...
