Project description

Na območju Vodnikovega trga (Ljubljanska tržnica) v Ljubljani je predvidena izvedba podzemne garažne hiše. Analiza podaja hidrogeološke pogoje izvedbe gradbene jame ter interakcije predvidenega posega s podzemno vodo v času gradnje in v času obratovanja.

Technical properties

For the hydrogeological characterisation of the area, 4 additional piezometers were installed in which hydraulic tests were carried out to characterise the hydrogeological properties of the individual lithological units. The piezometers are monitored for groundwater level, temperature and electrical conductivity over a period of at least one hydrological year. A numerical hydrogeological model of the construction pit has been developed to determine the conditions for the construction and operation of the underground garage. The model was built using the finite element method in the Hydrus software.
