Inženjerskogeološko istraživanje u svrhu projektiranja temelja stambenih zgrada na lokaciji Srebrnjak (Grad Zagreb)

U okviru ovog diplomskog rada provedeno je inženjerskogeološko istraživanje na lokaciji Srebrnjak. Svrha istraživanja je interpretacija inženjerskogeološkog modela padine koji služi kao podloga za projektiranje temelja devet stambenih zgrada. U okviru istraživanja provedeno je geodetsko snimanje, inženjerskogeološko kartiranje, geotehničko istražno bušenje s determinacijom jezgre i in situ pokusima (SPP), laboratorijsko ispitivanje fizičkih i mehaničkih svojstava temeljnog tla na poremećenim i neporemećenim uzorcima te mjerenje razina podzemne vode u bušotini. Determinacijom i interpretacijom jezgre te korelacijom bušotina utvrđeno da istraživanu parcelu izgrađuje 5 inženjerskogeoloških tipova naslaga relativno sličnih fizičko-mehaničkih svojstava. Površinske naslage čine dva inženjerskogeološka tipa, umjetne naslage (nasip) te deluvijalne/eluvijalne gline, dok vertikalno i lateralno heterogenu podlogu izgrađuju tri inženjerskogeološka tipa pliokvartarne starosti koje možemo podijeliti na gline visoke i gline niske plastičnosti te na heterogenu mješavinu krupnozrnastog i sitnozrnastog tla. Inženjerskogeološki model istraživane lokacije prikazan je u obliku inženjerskogeološka karta mjerila 1:500 te 5 inženjerskogeoloških profila mjerila 1:500.
Within this master's thesis engineering geological investigation has been carried out in the location in the Srebrnjak street. Aim of the investigation is the interpretation of the engineering geological model of the slope which serves as a basis for foundation design of nine planned residential buildings. Investigation included geodesy survey, engineering geological mapping, borehole drilling with core sampling, borehole logging and in-situ tests (SPT), laboratory tests of physical and mechanical properties on disturbed and undisturbed samples of foundation soil and groundwater level measurements. Determination, interpretation and correlation of borehole data gave an insight on the geological structure of the investigated location. Deposits were divided into five engineering geological units ( engineering geological types) of relatively similar physical and mechanical properties. Superficial deposits are made of two engineering geological types, artificial deposits and diluvial/eluvial clays, while the vertically and laterally heterogeneous Plio-quaternary bedrock is made of three engineering geological types which are divided into high plasticity clay deposits, low plasticity clay deposits and heterogeneous mixture of coarse–grained and fine–grained soil. Engineering geological model of the investigated location is presented in a form of engineering geological map and five engineering geological profiles at the scale of 1:500.
