<p>This Geoguide presents a recommended standard of good practice for rock cavern application and design in Hong Kong. The contents of this guide are derived from Scandinavian practice with suitable modifications for application in Hong Kong.</p>

<p>This paper shows the results of the analysis of the data acquired during the excavation of the new &ldquo;Fabriano&rdquo; Tunnel along the railway line from Rome to Ancona in Italy. The comparison between the results of the analyses and the consolidation ...

<p>Unloading failure of rocks, especially highly stressed rocks, is one of the key issues in construction of underground structures. Based on this, analytical models for rocks under quasi-static and intensive unloading conditions are established to study the ...

<p>Although many intact rock types can be very strong, a critical confining pressure can eventually be reached in triaxial testing, such that the Mohr shear strength envelope becomes horizontal. This critical state has recently been better defined, and correct ...

Unlike fragmental rockfall runout assessments, there are only few robust methods to quantify rock-massfailure susceptibilities at regional scale. A detailed slope angle analysis of recent Digital Elevation Models (DEM) canbe used to detect potential rockfall ...

Yosemite Valley poses significant rockfall hazard and related risk due to its glacially steepened walls and approximately 4 million visitors annually. To assess rockfall hazard, it is necessary to evaluate the geologic structure that contributes to the destabilization ...

Landslide Brus was occurred in April 2005, near Brus village in Istria, Croatia. Landslide is typical block sliding and landslide body consists of practically unique flysch rock mass block, 150 m long and 35 m wide. Sliding was occurred momentary, without ...

<p>In this paper we examine if it is possible to determine the mechanical REV from (Representative Elementary Volume) analyses carried out on geometrical parameters, which don't require mesh making.</p>

Support design for jointed rock masses can be approached in several ways. When designing support systems for these conditions, the potential block sizes and likelihood of occurrence should be considered. This paper outlines an approach whereby probabilistic ...

<p>In this paper an analysis of in situ rock mass modulus measurements for a wide range of rock types from China and Taiwan has resulted in two new equations for estimating rock mass deformation modulus.</p>
