Abstract

U ovom diplomskom radu opisana su geotehnička sidra. Prvi dio rada počinje klasifikacijom i svojstvima gline. Kompaktnost i plastičnost gline ovisi od količini postotka vode u glini. Glina se sastoji od glinenih minerala od kojih su najzastupljeniji kaolinit,montmorilonit,ilit. Opisani su načini stabilizacije kod klizišta i građevinske jame u kojima se sidra koriste.
Glavni dio rada počinje elementima te klasifikacijom sidra. Zatim je opisan sami postupak ugradnje sidra koji se sastoji od pripremnih radova, izrade bušotine,ugrađivanja i injektiranja sidra te prednaprezanje sidra. Prednaprezanje je vrlo bitan postupak u funkciji sidra. Nosivost ovisi o svojstvima tla i tehnologiji ugrađivanja sidra. Kako bi održali stabilnost građevine ne smije doći do sloma u dijelovima sidra i okolnom tlu. Ispitivanje sidra osiguravamo sigurnost objekta.
Kasnije je objašnjeni postupak sidrenja u glinovitom tlu. Na kraju rada opisan je praktičan primjer primjene sidara na dogradnji poslovne zgrade.

Abstract (english)

Geotechnical anchors are described in this diploma thesis. The first part of the paper begins with the classification and properties of clay. The compactness and plasticity of the clay depends on the amount of percentage of water in the clay. Clay consists of clay minerals, the most common of which are kaolinite, montmorillonite, and illite. Methods of stabilization in landslides and construction pits in which anchors are used are described.
The main part of the work begins with the elements and the classification of the anchor. Then, the process of anchor installation is described, which consists of preparatory works, drilling, installation and injection of anchors and prestressing of anchors. Prestressing is a very important procedure in the function of anchors. Load capacity depends on soil properties and anchor installation technology. In order to maintain the stability of the building, there must be no breakdown in the parts of the anchor and the surrounding ground. Testing the anchor ensures the safety of the facility.The anchoring procedure in clay soil is explained later. At the end of the paper, a practical example of the application of anchors on the extension of an office building is described.
