Seismic effects of blasting during the blasting for excavation of channel for suction pipeline of hotel Marjan : master's thesis

Podvodno miniranje u svrhu rekonstrukcije cjevovoda hotela Marjan u Splitu predstavljalo je visoko rizično miniranje zbog blizine stambenih objekata. Prilikom svakog miniranja obavljeno je mjerenje seizmičkih utjecaja miniranja na okolne objekte. Na osnovu izmjerenih brzina oscilacija probnog i svakog idućeg miniranja obavljena je korekcija parametara miniranja za svako naredno miniranje. Masa eksplozivnog punjenja po stupnju otpuvcavanja korigirana je na način da izmjerene oscilacije tla budu u granicama dozvoljenih oscilacija propisnih normom HRN DIN 4150.Abstract: Underwater blasting for reconstruction of pipelines Hotel Marjan in Split was represented high-risk blasting because of residential buildings nearness. For each blasting measurement of seismic effects of blasting on surrounding objects was done. Based on the measured velocity of oscillation, correction of blasting parameters for every following blasting was performed. Mass of explosive charge per delay was corrected in the way that measured velocity of oscillation were within the permissible limits allowed by HRN DIN 4150
