Rockyfor3D is a simulation model that calculates trajectories of single, individually falling rocks, in three dimensions (3D). The model combines physically-based, deterministic algorithms with stochastic approaches, which makes Rockyfor3D a so-called ‘probabilistic ...

<p>This report outlines detailed 3D rockfall modelling of multiple areas within the Canterbury Port Hills near Christchurch, New Zealand. It includes a rockfall hazard assessment for the area. This analysis will provide Canterbury Earthquake Recovery Authority ...

The standard design tools for buildings and civil engineering infrastructure are not prepared for working with real world subsurface information that originate from the 3D geological and geotechnical models. Also GIS standards (as the OGC standard CityGML) ...

Geosynthetic reinforcement over a grid of piles in soft soil can help transfer loads to the piles, and reduce settlements. This first part of a three-part study utilises a three-dimensional thin-plate model of the geosynthetic. The von Ka´rma´n theory, which ...

El Teniente Division of CODELCO is conducting a pre-feasibility engineering evaluation of Rajo Sur project in Chile. This project involves construction of an open pit to mine a copper deposit near the southern border of the caving subsidence crater high in ...

Over several decades in Southern Africa the advance rates when sinking vertical shafts have declined significantly. The upside has been a substantial improvement in shaft bottom conditions and a commensurately improved safety performance, with an increasing ...

This paper describes experience gained in the application of terrestrial digital photogrammetry and terrestrial laser scanning for the characterization of the structure of high mountain rock slopes and large landslides. A methodology allowing the creation ...

A factor limiting preliminary rockfall hazard mapping at regional scale is often the lack of knowledge of potential source areas. Nowadays, high resolution topographic data (LiDAR) can account for realistic landscape details even at large scale. With such ...

Current production level design guidelines in block caving mines are based on the concept of interaction of movement zones and the spacing of draw-points at which mass flow is achieved. The limit of the isolated movement zone (IMZ) interaction has been determined ...

Protection forest management requires reliable data on the structural characteristics of forest stands with high spatial resolution, which could be delivered by airborne laser scanning. We subtracted a digital surface model (DSM), derived from the last LiDAR ...
