| abstracts | This paper reports results from 1g model tests carried out under single gravity on a skirtedfoundation installed in sand and subjected to a rapid uplifting force. The effects of displace-ment rates ranging from 5 mm/s to 450 mm/s on the ultimate capacity, suction pressure insidethe skirt compartment, and time of extraction were investigated. Test results indicate that thedisplacement rate significantly affected the magnitude of uplift resistance, as well as the magni-tude of suction under the foundation lid, but had little effect on the relationship between stressand the displacement of the foundation. The shapes of the uplift capacity-displacement curveand the suction-displacement curve were similar for all experimental displacement rates. |

| abstracts | The paper presents a numerical simulation of the development of a catastrophic landslide ina sandstone quarry and methods of reconstructing the quarry to its previous condition frombefore the landslide. The important objective of the paper is to present the capabilities ofthe numerical method used in the analysis of the landslide process, namely the Distinct El-ement Method (DEM). This method is poorly known, though it is capable of solving impor-tant geotechnical problems in which massive displacements are modelled. The features of themethod are presented on the basis of a case study. Therefore a numerical analysis is carriedout to show the performance of DEM in generating a displacement of several dozen meters inthe example of a catastrophic landslide that occurred some years ago in a sandstone quarry.This engineering problem makes it possible to describe and analyse the mechanisms, causesand consequences of the landslide. |
