... ABSTRACT: Geotechnical monitoring is an indispensable part of geoscientific investigation for all phases of the development of repositories in deep geological strata. In the mine of Morsleben in Germany it is applied in the already operating repository while in the salt dome of Gorleben...

... ABSTRACT: The paper presents the results of physical (geomechanical) model investigation of fractured rock behavior for validating the overall stability of openings excavated in the rock massif for a power house of a hydropower plant. Three types of tests were performed by geomechanical...

... history describes the investigation, design, construction, and settlement performance the stockpiling area. Limited geotechnical data lead to pragmatic design with implications for reliability of settlement performance. Investigation and design included two trial embankments, drillholes, static cone...

... investigations, risk analysis, assessment of the underground structures, etc. All these issues must be considered in the search of the optimum use of underground space and, in addition, it must be remembered that the use of underground space is not an end in itself. Geoengi- neering considerations influence...

... ABSTRACT: An investigation aimed at categorising and compiling the technical and environmental aspects of cement and chemical grouts has been carried out. This has resulted in a comprehensive compendium, which includes a systematic strategy proposed to be used by the Swedish National Road...

...APPLICATION OF GEOPHYSICAL METHODS IN A GEO- ENVIRONMENTAL INVESTIGATION Patricia do Lago Grazinoli, Eurípedes do Amaral Vargas Jr., Ariovaldo da Costa and José Manuel de Oliveira1 ABSTRACT This paper presents the results obtained with two geophysical methods ground penetrating radar (GPR...

... ABSTRACT: This paper reports a case study of site investigation and remediation of a soil contaminated with Trichloroethylene (TCE) at a factory site still in operation. Early investigation indicated contamination of the ground surrounding a warehouse building. This soil was excavated...

...SELF-HEALING PROPERTIES OF CLAYEY SOILS K. Mallwitz1 ABSTRACT This paper presents the results of an investigation on the self healing behaviour of clayey soils with respect to hydraulic conductivity in liner systems of waste deposits using triaxial and oedometer tests. Several types of cracks were...

... ABSTRACT: Geotechnical and environmental investigations of buried landfill by drilling or penetration testing are difficult and hazardous. Uncontrolled fill materials can be highly variable, however, landfill is typified by low density, low seismic velocity and high seismic attenuation...

... at the toe of the embankment and the movement was sufficient to lead to serviceability failure of the wall. This paper reports on the investigation into the serviceability failure of this wall and its interaction with the reinforced embankment. The paper also offers general advice on the design...

...NUMERICAL INVESTIGATIONS OF INCLINED LANDFILL LINER SYSTEMS Helmut MeiBner1, Katja Abef ABSTRACT Liner systems of landfills placed on slopes are subjected to stress due to displacements of waste. Waste displacements result from settlements and from subsidences of waste material in the landfill...

... and environmental geological maps. The Geological Survey of Sweden, SGU, has initiated projects to satisfy some of the above-mentioned needs. SGU therefore intends to produce geoscientific information concerning the most densely populated areas of Sweden. From this year (2000) investigations have been started...

... and as such are not compatible with the concept of sustainable development which calls for the re-use of such sites. The key to effective re-use of such land is harmonized management of ground investigation, risk assessment and clean-up strategies. One of the case histories considered involves a site investigation for a relief...

... which guides the planning of the investigation and the design and construction of the project. This model develops progressively to be site specific, as the understanding of the local geology improves during the development of the project. The approach starts with an initial series of simple...

Merli4 ABSTRACT The paper deals with an examination of the geotechnical aspects of a plan to renovate the Parco delle Rimembranze , next to the Teodorico Mausoleum...

... changes with depth, these elastic waves are dispersive in nature, which means that they travel at a velocity that is dependent upon frequency (or wavelength). CSWS is a particularly attractive method of investigation for landfill engineering due to the non-intrusive nature of the method that eliminates...

.... INTRODUCTION The time of garbage dump seen as a pile of wastes is over. Our concern is to improve the environmental quality of these sites. The aim of the investigation described here is to compare the behaviour of clay - the mechanical properties of which as landfill bottom liner have long been proved - wet...

... ABSTRACT: In this report, the present author discussed on the actual situation of coastal pollution by the drifted garbage in the Japan Islands. The investigations of coastal environment were performed at a large number of seashores in the Sakishima Is. (Okinawa), Honshu and Hokkaido districts...

... of tunneling on existing structures is a major concern. This report addresses the main aspects of tunneling and underground works performed in soils and soft rocks. A summary is presented of the main features related to construction techniques, ground investigations, design methods, and instrumentation...
