...STABILITY OF TUNNELS IN CLAY WITH OVERLYING LAYERS OF COARSE GRAINED SOIL Richard J. Grant1 and R. Neil Taylor2 ABSTRACT The stability of tunnels constructed in clay with overlying layers of coarse grained soil is examined using data from centrifuge model tests. Results show that the stability...

... 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...

... ABSTRACT: The recent advances in ground anchor technology and the related techniques of cable bolting and rock bolting are reviewed. Collectively the technology associated with the three techniques enable design engineers to address stability problems over a range of scales and in a range...

... reclamation for diverse uses. In the planning and design of land reclamation, the stability of the fill resting on foundation soils is important. However, the analysis method provides no information on the change of stress and strain in the soil. For a detail understanding of the problem, the finite element...

... been used to ensure the stability of the foundations and abutments, and to reduce seepage to acceptable levels. INTRODUCTION Background "No structure grips the ground so closely as a dam. It holds on at its base and at its flanks… In other words, a dam is made up of two parts: the artificial dam...

... ABSTRACT: Soil nailing is an earth retaining technique used to stabilise existing slopes and support excavations. The stability post construction can change due to variation in groundwater, resulting in a reduction of effective stress in the soil. Nine centrifuge model experiments were...

... ABSTRACT: Building a high embankment on soft alluvial deposits within the constraint of a short construction period has always posed challenges to geotechnical engineers. Other than stability, settlement of the embankment has to be controlled. In the construction of a bridge embankment project...
