The right bank high slope of the Dagangshan Hydroelectric Power Station is located in complicated geological conditions with deep fractures and unloading cracks. How to obtain the mechanical parameters and then evaluate the safety of the slope are the key problems. This paper presented a displacement back analysis for the slope using an artificial neural network model (ANN) and particle swarm o...

In spring 2007, a large rock avalanche descended onto the Morsárjökull valley glacier in southeast Iceland, leaving one fifth of the glacier buried. The insulating effect of the deposit on the ice was quickly observed as a difference in the ablation between the exposed ice and that under the deposit. After three melt seasons, the ice surface under the deposit was 29 m above the surrounding glac...

A systematic method is presented for evaluating the slope safety utilizing multi-source monitoring information. First, a Bayesian network with continuously distributed variables for a slope involving the factor of safety, multiple monitoring indexes and their influencing parameters (e.g. friction angle and cohesion) is constructed. Then the prior probabilities for the Bayesian network are quant...

Quantitative classification from the Slope Mass Rating (SMR) has introduced an empirical assessment for rock slope stability rating. This enables us to foreseethe magnitude and susceptibility of mass failure towards adjacent infrastructure human life. In this study, quarry was classified using SMR system kinematic analysis before being correlatedwith geohazard vulnerability assessment. Geologic...

Observations from 145 submersible dives are used to create a database of mid-ocean ridge scarp topography and lithology. Seafloor lithologies are classified into extrusives, basaltic talus, dykes, gabbros and serpentinites, and the dive locations are broadly classified according to whether they are close to transform valleys and as a function of ridge spreading rate. The database is used to det...

This article examines the merits of using finite element analysis versus limit-equilibrium methods for slope design and analysis Geomechanics software used worldwide by geotechnical engineers Article prepared for RocNews Summer 2004 software tools for rock and soil

l f Discominuity persistence has a major effect on rock mass resistance (strength) but, as direct mapping ofdiscominuities imemal to a rock mass is not possible, persistence is a difficult parameter to measure. As a result, the conservative approach of assuming full persistence is often taken. /n this paper a method is developed for relating rock mass stability and hence persistence to the geom...
