Construction pit for the crossing of new sewage line under Kokra river |
Secondary abstract: |
The thesis deals with geostatic analysis of temporary excavation pit for installation of pump station and service shaft. They are part of the project named Renewal of public sewerage, waterwork and road reconstruction in Savska cesta in Kranj. Nearby buildings, local road, Kokra river and design depth of pump station dictate realization of temporary protection of construction pit under phreatic level. Analysis are executed analytically and numericaly using computer program Plaxis. Analytically soil stresses are calculated by Rankine earth pressure theory, otherwise the computer program Plaxis is based on finite element method (FEM). We checked folowing examples of protection of construction pit: cantilever pile wall, anchored pile wall, struted pile wall, well and sheet piling frame. Eurocode standard EC7 is considered in calculations. Various examples are also analysed and compared by economical and technological criterion. |

Abstract (ePrints): |
Diplomsko delo obravnava geostatično analizo varovanja gradbene jame črpališča in revizijskega jaška projekta obnove javne kanalizacije, vodovoda in vozišča na območju Savske ceste v Kranju. Bližina objektov, reka in projektirana globina črpališča narekujeta izvedbo začasne gradbene jame s podprtimi brežinami pod gladino podtalnice. Geostatična analiza je izvedena analitično in z računalniškim programom PLAXIS 8.2 profesional version. Pri analitičnem računu so zemeljski pritiski računani po mejnih stanjih Rankina, medtem ko računalniški program preračunava primere po metodi končnih elementov (MKE). Preverili smo sledeče izvedbe varovanja: konzolna pilotna stena, sidrana pilotna stena, razprta pilotna stena, vodnjak in zagatna stena. Pri računanju so upoštevani veljavni Evrokod standardi. Različice varovanj gradbenih jam so primerjane tako po tehnološkem kot tudi po ekonomskem kriteriju. |
