.... Therefore, the displacement transducers must be in locations where the risk is that additional displacements originating from deficiencies in the test system will be measured causing too low normal loads to be applied. Herein, this issue is investigated in a new 5 MN direct shear test setup. The system...

... and geotechnical investigation for timely completion of projects. Lots of survey and Investigation is carried out to ascertain the geological and geotechnical feasibility of the hydro projects and for preparation of DPR. Construction of large caverns for power house presents challenges in terms of geotechnical...

... conditions were found favourable in general. However, comprehensive investigations revealed weakness planes crossing the cavern. The support system was determined by joint evaluation of empirical methods, wedge analysis and the 2-D finite element analyses. Due to the complicated geometry of the cavern...

... and underground environment. The surveys confirmed that there were no visible signs of instability in the areas where the surveys were done. Advantages and limitations exist for the methods used to complete the survey and use the survey results during this investigation. These will be discussed in this paper...

... to the current state of the art. For many years, an intensive scientific investigation has been carried out within the frame-work of repository research with continuous optimization of the rock mechanical modelling of the material behavior of rock salt. From the elaboration of the research results...

... outlined. The undeniable degree of financing preliminary investigations because of high forthright expenses is regular for the vast majority of the underground and tunnel projects. However, there are additional risks such as the geological uncertainty mainly related to the robustness of the preliminary...

... as the guiding one, studied with the range of 25–75% of ultimate stress. 503 rock samples have been investigated for this analysis. The elastic behaviour of rocks and the range of their elasticity are of crucial importance in rock engineering. In solving problems in mining engineering or tunnelling, the change...

... Abstract Non-destructive investigation and analysis of inner structure of rock samples by an X-ray CT is an important instrument for better insight into properties of rock materials related to the geometrical shape and arrangement of individual construction elements, the spatial distribution...

... ABSTRACT: As in the case for all construction structures also for the construction of the Dams and Hydroelectric Power Plant (HEPP) Constructions, construction time and safety of civil structures are very important parameters. Detail investigations during planning of construction and sensitive...

... and prevent future instabilities. This paper presents the investigations and interpretations of the structural geology, the impact on the stope stability, pillar behaviour and support. 1 INTRODUCTION Rowland Shaft is one of Lonmin's first generation vertical shafts, extracting both the Merensky and Upper...

... and they are still used today. The authors have performed some site investigations and surveying of these remaining stone bridges. In this study, the response and stability of stone bridges are investigated using finite element method under various loading conditions and the results of the investigations...

... ABSTRACT: In the course of an extensive investigation campaign for the Lagobianco pumped storage project, laboratory tests as well as several in-situ tests were performed. Among these in-situ tests, measurements of in- situ stresses were carried out which are intrinsically afflicted...

... ABSTRACT: Magdalena Colliery is experiencing guttering related fall of ground incidences at some locations that are causing production disruptions and safety concerns. This paper investigates the possible reason(s) behind guttering by taking into account the rolling nature of the coal seam...

... ABSTRACT: The geometrical parameters of 639 discontinuities that surveyed in powerhouse cavern of Rodbar Lorestan pumped storage power plant project have been investigated by scanline and areal sampling methods. As regards the processing and correction of bias types, one bedding and three...

... investigations and a GNSS monitoring program, are presented. 1 INTRODUCTION The observation of landforms related to the presence of ancient large mass movements is not very common, due to the constant erosion carried out by runoff waters and sea waves, along the coastline; moreover, landslide...

... discontinuities were carried out. Field geophysical investigations and rock quality estimates through the survey of exposed rock faces are also reported and discussed. Significance of shear strength parameters at different scales has also been evaluated by comparing shear strength results from small scale...

... characteristics of host rocks, (b) the assessment of in-situ stresses, (c) the investigation of instabilities and their extent, (d) short- and long-term stability analyses of the most famous underground city called Derinkuyu, and (e) long-term surveys on climatic conditions in some of the selected historical...
