... ABSTRACT ABSTRACT: This case study presents a high resolution 3D imaging and assessment system and its application during the construction of a planned nuclear waste repository in Hungary. During the drill and blast excavation of two inclined access tunnels of about 1.800 m each the system...

.... This section was chosen because it crosses some of the most rugged and challenging terrain along the Sea to Sky Highway alignment. The purpose of the Test Section was to assess the impact of construction on traffic mobility and de- velop design solutions for implementation during the remainder of the highway...

... 1 INTRODUCTION 1.1 Project The Nevada Power Company (NPC) is constructing the Harry Allen Mead (HAMD) 500 kV power transmission line, NPC s largest. Los Angeles De- partment of Water and Power (LADWP) owns a high power transmission line that traverses prime terrain in a pass formed from...

... plant was constructed in the Daejeon Science Complex in 2003. A pilot test using liquid nitrogen was conducted from January through August, 2004. In this paper, measured in-situ rock mass response from the pilot test are presented and analyzed. Overall, the results confirm that both construction...

... at depths of up to 1500m with excavation of bank rock volumes in excess of a half a million cubic metres. Such dimensions are at or beyond the limit of conventional rock engineering practice and construction will be a major undertaking. In the US, the Long Baseline cavern would be one of a number of large...

... ABSTRACT ABSTRACT: The backdrop for this research paper is the tunnelling that is currently nearing completion in the Epirus and Western Macedonia regions of Northern Greece, as part of the Egnatia Odos Highway construction. Highly deformed and altered sediments and low grade metamorphic...

... ABSTRACT ABSTRACT: Under China’s great plan to develop the western part of the country, infrastructure development is booming in the region and numerous construction projects have sprung up everywhere. Geotechnical work thus requires special attention in the region. This paper presents...

...1 INTRODUCTION Tunneling beneath the groundwater table causes changes in the state of stress and the pore water pressure regime. In such tunneling problems, there are three important issues that have to be addressed during design and construction stages including con- struction, stability...

... ABSTRACT ABSTRACT: We constructed a landslide susceptibility map of a specific dam site in Korea using GIS technique. Pack’s (1995) Stability INdex MAPping (SINMAP) technique, a stability index approach to terrain stability hazard mapping based upon the infinite slope stability model...

... ABSTRACT ABSTRACT: Shahriar dam is a double-curvature concrete arch dam which is under construction near the town of Mianeh in northwest of Iran. The alluvial sediments in the riverbed of the dam are underlain by lowstrength clay and therefore are likely to cause slope stability failures...

... and construction of an approximately 10.4-km long water conveyance tunnel, and associated intake and outlet structures. The intake is located upstream from the Niagara Falls and the outlet is near the existing Sir Adam Beck (SAB) hydroelectric plant. The project is being constructed following the Design/Build...

... ABSTRACT ABSTRACT: The Susten Pass road in central Switzerland was constructed from 1938 to 1946 and follows the topographic feature caused by the northern boundary of the intrusive body, known as the Aar massif, in the central Alps. The road has since become a major tourist attraction...

.... The larger dams such as Bennett, Mica, Revelstoke (Fig. 2), Peace Canyon, Seven Mile and Terzaghi were designed and constructed in the 1950 s to 1980 s. Many of the smaller to medium- sized dams such as Alouette, Stave Falls, Ruskin and Whatshan were constructed in the 1910 s to 1950 s by private electricity...

.... Experiments will investigate methods of in situ characterization using geophysical methods, extend our understanding of complex interactions of coupled processes which control the evolution of the dynamic Earth, and which extend methods of excavation and construction, especially at extreme depths...

... ABSTRACT ABSTRACT: The observational approach in rock and underground engineering often is interpreted as “design as you go”, implying that there is no or only a very basic design available prior to start of construction. Spectacular cost- and time overruns are the consequence of a lack...
