The hydrogeological investigations are inevitable in the whole process in defining of engineergeological field characteristics and the drafting of landsllides rehabilitation project, but the main goal of these investigations is the groundwater quantities calculations in critical sections of landslides. For gain of exact input parameters for groundw...

Earthquakes are one of the biggest hazards of humanity. Even today it is not possible to predict the exact magnitude, location and time of an earthquake, but, nevertheless, modern seismology and science are able to point to the potential danger and risk of earthquake-like movements in an area, at one time. Some of the signs that announce the earthq...

Wells conditions are different in wide range of temperature and depth. Cement slurries in such conditions have to remain pumpable and after setting to stay homogenous in production well life. For cementing operations in wide range of temperature and pressure and to accommodate cement slurries for individual well requirements more than 50 additives ...

During the past two decades, rapid advances in information technology have improved the accuracy and capabilities of optimization techniques. Unfortunately, great number of optimization methods in civil engineering has not found implementation in practice, mainly because the problems were treated only from mathematical point of view, disregarding a...

Before the electronic distance meters appears the angles measuring dominated in geodetic networks. Development of distance measuring technology and appearance of automated total stations almost equaled the efficiency of measuring angles and distances. This fact allows designer of geodetic networks to combine angles and distances in order to achieve...

Grad Bijeljina sa oko 70 000 stanovnika, nalazi se u sjeveroistočnom dijelu Republike Srpske, Bosna i Hercegovina. Nagli prirast stanovništva u posljednjih 15 godine, te povećan broj automobila u gradu, stvorili su saobraćajnu gužvu, kako po pitanju kretanja motornih vozila, tako i njihovog parkiranja. Ako se pri tome ima u vidu, da su automobili u...

Izgradnja Termoelektrane Ugljevik 3, snage 2 x 300 MW, zahtijevala je detaljnije proučavanje terena, posebno sa aspekta njegove seizmičnosti. Na terenu je ranije konstatovan rasjed u dijelu gdje su planirani budući objekti termoelektrane. Prethodnim terenskim istražnim radovima potvrđeno je njegovo prisustvo, što je što je zahtijevalo detaljnije an...

Već više od trideset godina traju istraživanja na temu naglih promjena (iznenadnog povećanja ili smanjenja) koncentracije radona koja prethodi zemljotresu na određenoj lokaciji U ovom radu prikazani su rezultati mjerenja koncentracije aktivnosti radona u vodama seizmički aktivnih zona Tuzlanske regije. Korištena je i opisana metoda mjerenja radona ...
