n this study, a large arch-gravity Moste Dam was analyzed, where an automated system for the measurements of horizontal displacements of the upper part of the dam was established. Two-dimensional (2D) and three-dimensional (3D) analyses of dam behavior, taking into account the earth pressures and th ...

The Slovenian section of the Drava River is 133 km long, and over this distance it has a descent of 148 m. Eight HPPs are located on this section (six directly in the river course, whereas the other two in derivation channels of the river). Ten concrete gravity dams, with a structural height between ...

A typical retaining structure built with large-diameter bored piles in soft clastic rock, and sup-ported by pre-stressed permanent ground anchors, is discussed. Step-by-step back analyses were performed. A simplified geological structure was first used in the analyses, together with a simple Mohr-Co ...

The Mavčiče concrete gravity dam, part of the corresponding hydro-power plant, was built on the Sava River, in Slovenia, in 1986. It has a maximum structural height of 38.5 m, and the dam crest has a length of 149 m. The dam structure consists of an erection bay, a machine hall, and two spillways, f ...

This paper deals with the heat transfer analysis of the 63-year-old and 60-m-high Moste concrete arch-gravity dam, located in Northwest Slovenia. The analysis was performed after a new sophisticated monitoring system had been established, making it possible to perform continuous measurements of the ...

This study presents a procedure for modeling the heat transfer process in a concrete dam, taking into account the time-varying boundary conditions on the upstream and downstream sides of the dam (i.e., the water level of the reservoir, spillover, insolation, and shading) which affect the temperature ...

V doktorski disertaciji je predstavljen algoritem za modeliranje prehoda toplote skozi betonsko pregrado, ob upoštevanju časovno spremenljivih robnih pogojev na gorvodni in dolvodni strani pregrade (gladina vode v akumulaciji, prelivanje vode čez krono pregrade, osončenost in osenčenost), s katerim ...
