Abstract

Trajnu denivelaciju terena potrebno je osigurati stabilnom geometrijom kosine ili izvedbom potpornog zida.
U radu je dan prikaz rješenja osiguranja denivelacije uporabom armirano betonskih potpornih zidova s naglaskom na T oblik presjeka.
Armirano-betonski potporni zid je tip potporne konstrukcije, gdje se pravilnim odabirom dimenzija i količine armature postiže optimalno rješenje. U radu je prikazana podjela potpornih konstrukcija prema nekoliko kriterija, te je prikazan način njihova dimenzioniranja.
Optimalan odabir dimenzija potporne konstrukcije nastaje kao posljedice provedbe odgovarajućih proračuna, odnosno analize graničnih stanja sloma i uporabivosti same konstrukcije i temeljnog tla.
Eurokod je jedinstveni sustav normi za projektiranje građevinskih konstrukcija koji je razvijen u Europi. Eurokod 7, koji je sastavni dio cijelog sustava, odnosi se na geotehničko inženjerstvo. Generalni pristup proračunima sastoji se u primjeni parcijalnih koeficijenata sigurnosti na vanjska djelovanja, materijal i otpornost.
U radu je dan numerički primjer izgradnje potpornog zida u Kostrena Barbara, Bakar. Statički proračun potpornog zida uključuje analizu relevantnih graničnih stanja gravitacijskog zida - nosivost temeljnog tla, globalnu stabilnost, prevrtanje i klizanje zida, te njegovo dimenzioniranje, odnosno određivanje potrebne armature.

Abstract (english)

Permanent leveling of a terrain must be ensured by a stable slope geometry or the construction of a retaining wall.
The master thesis presents a solution for ensuring leveling using reinforced concrete retaining walls with an emphasis on a T - shaped profile.
Reinforced concrete retaining wall is a type of a supporting structure where the correct choice of dimensions and amount of reinforcement achieve the optimal solution. The master thesis presents the division of supporting structures according to several criteria and shows the method of their sizing.
The optimal selection of the dimensions of a supporting structure is a resultof the implementation of appropriate calculations, i.e. the analysis of the boundary conditions of a failure and the usability of a structure and a foundation soil.
Eurocode is a unique system of standards for the design of building structures which has been developed in Europe. Eurocode 7, which is an integral part of the whole system, refers to geotechnical engineering. The general approach to calculations consists of applying partial safety coefficients to external actions, material and resistance.
The master thesis presents a numerical example of the construction of a retaining wall in Kostrena Barbara, Bakar. Static calculation of the retaining wall includes the analysis of the relevant boundary conditions of the gravity wall - bearing capacity of the foundation soil, global stability, overturning and sliding of the wall and its sizing, i.e. determining the required reinforcement.
