Abstract

Građevinska jama je privremena konstrukcija koja se izvodi u sklopu izgradnje buduće građevine te osigurava iskop tla do projektirane dubine temelja. Projekt građevne jame ovisi o vrsti građevine i lokaciji na kojoj se izvodi, odnosno o vrsti i sastavu tla i prisutnosti podzemne vode. U ovom radu prikazuje se projekt izvođenja i zaštite građevne jame zgrade Hrvatske Lutrije u Zagrebu. Geotehničkim istražnim radovima na predmetnoj lokaciji te laboratorijskim ispitivanjima tla definiran je geotehnički model tla koji se sastoji od tri geotehničke jedinice. Parametri tla potrebni za projektiranje određeni su korelacijama s rezultatima terenskih i laboratorijskih ispitivanja, ali i izravno iz laboratorijskih ispitivanja. Modeliranje i proračun provedeno je u programu GeoStudio, a obuhvaćena je naponsko deformacijska analiza građevne jame s analizom procjeđivanja vode. Iskop građevne jame do projektirane dubine proveden je u pet faza, a građevna jama osigurana je armirano-betonskom dijafragmom i s dva reda geotehničkih aktivnih sidara.

Abstract (english)

A construction pit is a temporary structure that is carried out as a part of constructing new building and ensures the excavation of the soil to the designed depth of the foundation. The design of the pit depends on the type of the structure and the location where it is constructed, that is, on the type and composition of the soil and the presence of groundwater. This master’s thesis presents the protection of the construction pit of the Croatian Lottery building in Zagreb. A geotechnical soil model consisting of three units was defined by geotechnical investigation works at the site and laboratory soil tests. Soil parameters required for the design were determined by correlations with the results of field and laboratory tests but also directly from laboratory tests. Analyses of the construction pit were carried out in the GeoStudio program and included the stress-deformation analysis with the water seepage analysis. Excavation of the construction pit to the designed depth was carried out in five stages, and the construction pit was secured with a reinforced concrete diaphragm and two rows of geotechnical active anchors.
