20.500.12556/DKUM-46884 Idejna zasnova sanacijskih ukrepov za zmanjšanje ogroženosti premostitvenega objekta THE IDEA SCHEME OF REDEVELOPMENT MEASURES FOR HAZARD REDUCTION OF A BRIDGING STRUCTURE Projektna naloga obravnava zasnovo potrebnih konstrukcijskih ukrepov za zmanjšanje ogroženosti stebra viadukta, ki ga ogroža premikanje (lezenje) zemljin na pobočju širšega obsega. Analizirane so stabilnostne razmere izvedbe cca 11.0 m globokega izkopa elipsoidne oblike v zaledju temeljev ogroženega stebra viadukta. Z izvedbo izkopa bo dosežena razbremenitev temeljnih vodnjakov, ki jih ogrožajo dodatni zemeljski pritiski zaradi lezenja cca 10 do 11 m debele površinske plasti apnenčastih gruščev na pobočju nad kritičnim stebrom viadukta. Dokazana je izvedljivost projekta v pogojih postopnega izkopavanja ter dodatnega sidranja spodnjega dela izkopa z geotehničnimi ali IBO sidri intenzitete cca 375 kN/m. Pri presojah stabilnosti so skladno z veljavnim standardom SIST EN 1997 upoštevani delni količniki za projektni pristop 3, kot to določa Nacionalni dodatek. This project assignment deals with the scheme of required constructional measures for hazard reduction of a viaduct pillar that is endangered by ground moving in a wider range of the slope. We made analyses of stability conditions, of an approximately 11.0 metres deep ellipsoid shaped excavation, in the surroundings of the endangered viaduct pillar foundation. With this type of excavation we will reach a palliation of foundation wells, which are endangered by extra ground pressure because of sliding of an approximately 10 to 11 metres thick superficial layer of limy gravel on the slope above the critical viaduct pillar. Feasibility of the project is established, under the terms of gradual excavation and extra anchoring of the lower part of the excavation, with geotechnical or IBO anchors with the intensity of approximately 375 kN/m. Partial quotients for project approach 3, defined by the National addition, are complied with stability estimations in accordance with the valid standard SIST EN 1997. gradbeništvo lezenje pobočja sanacija izkopi geotehnična sidra civil engineering slope sliding redevelopment excavations geotechnical anchors true true false [N.
