Abstract

V diplomski nalogi je predstavljen praktičen primer načrtovanja ukrepov, ki omogočajo trajno stabilnost, izboljšajo nosilnost mehkih temeljnih tal in zmanjšajo njihova posedanja pod težo predvidenega nasipa, na odseku hitre ceste Koper – Dragonja, ki poteka po Vanganelski dolini, prekriti pretežno z aluvialnimi nanosi. Prvotno so analizirane terenske in laboratorijske preiskave, na podlagi katerih smo določili geološko-geomehanske razmere obravnavanega odseka in karakteristične pogoje izgradnje. V nadaljevanju smo izračunali predviden čas konsolidacije in velikost posedkov tal ter izvedli analizo stabilnosti nasipa in temeljnih tal. Obravnavali smo dve možni kombinaciji ukrepov. Prva kombinacija je bila vgradnja vertikalnih drenaž in bočnega nasipa, druga pa vgradnja gruščnatih kolov. Za obe varianti smo prikazali njihove osnovne lastnosti in postopek izračuna. Ukrepe smo dimenzionirali tako, da so zagotovili stabilnost temeljnih tal in pospešili konsolidacijo, da se je ta izvršila v predvidenem roku enega leta.

Secondary title: Foundation of a residential house on an unstable slope at Jelični Vrh
Secondary abstract: The thesis presents a practical example of the design of different measures for improving bearing capacity of poor bearing subsoil and for reducing and accelerating the subsoil settlement under road embankment. The embankment was planned on a section of the motorway Koper – Dragonja, passing through Vanganel valley, which is covered with alluvial deposits. Based on field and laboratory tests we determined the geological and geotechnical conditions of the section. We calculated settlements and the time required for soil consolidation and analyzed subsoil stability. Two different possible combinations of the most suitable measures were described. The first was the execution of vertical drains and lateral embankments, while the second was the placement of stone columns. For both alternatives, basic properties and methods of calculation were addressed. The proposed measures were dimensioned for ensuring proper stability and accelerating the consolidation process within the established one year time frame.
