... ABSTRACT: For the construction of the Kühtai embankment dam, a total fill volume of 6.9 mio m 3 is required. The main sources of the material are the overburden and hard rock of the Längental valley. The required rock material is produced in a quarry developed at the eastern reservoir slope...

.... Excavation of these shafts requires special techniques, and the performance is dependent on the quality of rock mass. Therefore, the selection of an efficient construction method for shaft excavation is most challenging work. This manuscript evaluates the challenges associated with the construction...

... ABSTRACT: Tunnels constructed in the rock formation have been considered safe against earthquakes. However, the 1995 Hyogo-ken Nanbu Earthquake (M7.3) caused large damages to mountain tunnels as many as to other structures. Tunnels are one of the important infrastructures, so the evaluation...

... ABSTRACT: Innovative delivery models attempt to deliver major construction projects within budget and on time. However, proving their efficiency is difficult because of a missing base for comparing innovative and traditional delivery models. Therefore, a common ground is mandatory, as given...

... ABSTRACT: The geo-uncertainty of underground projects most often leads to differences between foreseen and encountered geo-conditions. Dealing with this uncertainty is a major challenge as it often raises claims and complex contractual problems mostly related to the construction programme...

... ABSTRACT: The Semmering Base Tunnel (SBT) is about 27.3 km long and driven from the portal at Gloggnitz and three intermediate construction accesses in Göstritz, Fröschnitzgraben and Grautschenhof. The main components of the tunnel system are two single-track tunnels, cross passages...

... ABSTRACT: Slovenian Dinaric Karst is an extensive karst area, 800 km long and up to 150 km wide, which is distinguished by large, closed planes, and variety of relief forms, deep caves, underground rivers, and karst springs. The main challenge for the construction of new Divača-Koper railway...

... a deep and narrow canyon with high and steep rock slopes. The paper describes the challenges in the design and the construction of the EPC Contract for six tunnels with a total single bore length of approximately 20 km. This includes geological design, NATM excavation design and detailed structural...

... alignment radii turns and crossings with other LRT lines. The geological conditions feature different formations of limestone and dolomite. Karst is a known frequent phenomenon in the Jerusalem region which must be considered in the design and construction process. This publication describes the key...

... reveals how the radial grout curtains were executed within limestone-marl alternations. Taking the geological conditions into consideration, the success and quality of the grouting work was monitored by water pressure tests and by quantitatively evaluating the grouting records. Construction details...

... ABSTRACT: The design and the construction of underground caverns with low overburden in an urban environment is a sophisticated task. The project of an urban parking garage, which is built within a large span cavern construction is presented. Due to its low overburden, combined...

... ABSTRACT: Kameng Hydro Electric project (4x150MW), a ROR scheme was constructed by North Eastern Electric Power Corporation Ltd in the West Kameng District of Arunachal Pradesh, India. This project lies in the Lesser Himalaya consisting of Precambrian and Gondwana rock formations. A 14.5 km...

... ABSTRACT: The expansion/new construction of the railway line "Hanau-Würzburg/Fulda-Erfurt" is one of 13 infrastructural projects of the Deutsche Bahn AG that are to be implemented with high political priority. The new DB-Line Gelnhausen-Fulda is a sub-project of this infrastructure project...
