Abstract

Tema ovog diplomskog rad je temeljenje nadvožnjaka „Domagović“ na pruzi Hrvatski Leskovac-Karlovac. Kao rješenje odabrano je temeljenje na armiranobetonskim bušenim pilotima povezanih u grupi sa naglavnom konstrukcijom. Rad se sastoji od 8 poglavlja koji obuhvaćaju cjeline: općenito o nadvožnjaku Domagović, temeljenje na pilotima, provedeni istražni radovi, razrada podloga i odabir relevantnih parametara, geotehnički proračun, tehnologija izvedbe i program kontrole kvalitete. Na predmetnoj lokaciji piloti prolaze kroz 7 slojeva tla i to redom: glina, glinoviti šljunak, glina, glinoviti pijesak, glina, glinoviti šljunak i ponovno glina. Rade se provjere na osnu, bočnu nosivost i slijeganje pojedinačnog i grupe pilota kojima je dokazano da su granična stanja u prihvatljivim granicama, odnosno da je nadvožnjak siguran za izvedbu i uporabu. Za provjeru su odabrani stup i upornjak koji su izloženi najvećem opterećenju, odnosno upornjak broj 2 i stup broj 3. Također su vršene provjere na stupu broj 1 budući da su njegovi piloti kraći i ne prolaze kroz sve slojeve tla na predmetnoj lokaciji. 3D program RocScience-RS Pile pruža detaljan uvid u pomake i rezne sile koje će se prenositi sa svih stupova i oba upornjaka u pilote uvažavajući sve proračunske situacije.

Abstract (english)

The topic of this thesis is the foundation of the "Domagović" overpass on the Croatian Leskovac-Karlovac railway. Deep RC pilesare chosen as foundation solution, connected with cap. The thesis consists of 8 chapters that include units: generally about the Domagović overpass, pile foundations, carried out investigation works, documentation analysis and selection of relevant parameteres, geotechnical calculation and construction technology and quality control program. The soil on the subject location consists of 7 layers which include one after the other: clay, clayey gravel, clay, clayey sand, clay, clayey gravel and clay. Within the analysis the axial and lateral load capacity and settlement of one pile and the pile group was analysed, and it was proven that limit states are in acceptable range, which means that the overpass is safe for construction and use. For analysis, abutment number 2 and pier number 3 were chosen based on the fact that they are carrying largest loads. The checks were also carried out on pier number 1 since its piles are shorter and do not pass through all soil layers at the subject location. The 3D program RocScience-RS Pile provides a detailed insight into the displacements, moments and forces that will be transmitted from all piers and abutments to the piles, considering all design situations.
