The hydropower station is Chinese first oversea hydropower project but fully adopts the domestic design standards. The slope height is 80m~85m...

... mass characterization, based on the above-mentioned GSI quantification, utilizing both LiDAR and photogrammetry point clouds from several rock slopes. The proposed semi-automated methodology leads to the extraction of space-resolved GSI values for the entire slope, by automatically assessing...

... ABSTRACT: The anti-dumping layered rock slope is a common type of slope with various deformation and failure modes, complicated mechanics mechanism and many influencing factors. Through utilizing 3DEC to research on deformation and failure of toppling rock slope in 3D, ”curved book dumping...

... ABSTRACT: The natural formation of rock slopes can result in the initiation of complex failure processes, including the deformation and fracturing of intact rock and the displacement of large individual blocks. The presence of non-persistent discontinuities may also promote stress...

... ABSTRACT ABSTRACT: Footwall slopes refer to bedding rock slopes in which the slope face is parallel to a set of persistent discontinuities, which exist extensively in opencast mine. Stability evaluation of the footwall slopes is significant for theoretical study and engineering application...

... ABSTRACT: A simple jointed rock slope model is carried out in Discrete Element Method (DEM) to study the dynamic response of general jointed slope. Monitoring points in three directions are used to history the horizontal and the vertical acceleration, after acquiring the acceleration time...

... by the ratio of shear resistance to average shear stress on a pre-defined failure surface. However, the LEM approach neglects the local development of stress concentration in the discontinuities or crack/joints in slope. The most suitable approach in jointed rock slopes appears to be that which considers...

... Abstract: The Q-slope method provides a simple yet effective empirical means of assessing the stability of excavated rock slopes in the field. Intended for use in reinforcement-free road or rail cuttings or individual benches in open cast mines, Q-slope allows geotechnical engineers to make...

... Abstract: This paper explores two recent case histories involving major rock excavation and hydro power engineering projects. The Mayo B hydro power project is located in the Yukon, Canada. An unstable, 25 m (80 foot) high rock slope, comprised of relatively weak, low-grade metamorphic...

... high), Xiaowan arch dam (292m high), Jinping-I arch dam (305m high), Dagangshan arch dam (210m high) et al. The rock slopes in the dam sites are characterized by large-scale, high geostress and developed fractures. Although high safety factors are achieved in the optimized schemes of the dams...

... Abstract Present study investigates applicability, superiorities and impediments of point estimate methods (PEM) in probabilistic stability analysis of rock slopes. A rock slope which involves correlated non-normally distributed variables, is considered and probabilistic analyses are carried...

... sharp slope cut suffers from slope failures, rockfalls incidents, mainly in rainy seasons. The igneous rock masses are medium quality. The 40 m-height rock slope-cut along the road has no benches. The steep man-made rock slope cut is very close to the road, forming a potentially source for rockfalls...

... Abstract The crack propagation process may cause connecting the main fractures and discontinuities to break away the rock slopes and produce large-scale failures in rock masses surrounding large surface mines. In this research, the pattern of cracks propagation and coalescence in jointed rock...

... to an increase in the frequency of rock and icefall events. Ice build-up can destabilize a rock slope by expansive action (ice-wedging), by surcharging portions of the slope face, and by inducing an ice-dammed condition where water-pressures are allowed to build-up on discontinuity surfaces as a result...
