17 18 Over the last decade, terrestrial laser scanning and digital terrestrial photogrammetry techniques have 19 been increasingly used in the geometrical characterization of rock slopes. These techniques provide 20 innovative remote sensing tools which overcome the frequent problem of rock slope inaccessibility. 21 Comprehensive datasets characterizing the structural geological setting and geo...

slope stability analysis is a geotechnical engineering problem characterized by many sources ofuncertainty. in slope stability computations, some of these sources are encountered, such as geologicaldetails missed in the exploration program, estimation of soil properties that are difficult to quantifyand many other relevant factors. therefore, accurate reproduction of the spatial variability in ...

LiDAR (Light Detection and Ranging) scanners are increasingly being used to measure discontinuity orientations on rock cuts to eliminate the bias and hazards of manual measurements which are also time consuming and somewhat subjective. Typically LiDAR data sets (point clouds) are analyzed by sophisticated algorithms that break down when conditions are not ideal, eg. when some of the discontinui...

The Geological Strength Index (GSI) system is the basis of parameters used in Hoek-Brown failure criterion for rock mass strength estimation. author tested this and here suggests a modified GSI called Index-slope (GSIslope). combines two different existing approaches: Slope Mass Rating (SMR). purpose GSIslope to allow engineering geologists quickly evaluate stability natural excavated slopes or...

Roads are generally affected by slope failures, and these failures can increase when there weathered materials high rainfall. These circumstances occur in the sub-Andean zone of Ecuador. This is region where study area located. The stability a stratified rock slope, which affecting section highway E45, was evaluated. exposed to road, but upper part covered soil-type material dense vegetation th...

In Hong Kong, slope failure in weathered granite and volcanic rocks has been studied extensively, but the impact of hydrogeological conditions on slope stability has received much less attention. It is customary in Hong Kong to assume that the hydraulic conductivity (K) of weathered igneous rocks decreases with depth or as the rock mass becomes less weathered. Generally studies of groundwater f...
