Sekundarni naslov: | Design of reinforced-concrete diaphragm wall for the protection of excavation pit taking into account the seismic load |
Sekundarni povzetek: | The purpose of this Master Thesis is to analyse the reinforced-concrete diaphragm wall for the protection of deep excavation pit with a consideration to the seismic load. Firstly, nonlinear geostatic analysis of the diaphragm wall was performed, considering the ground model and technological process of construction. After the diaphragm wall was installed and the pit excavation was completed, dynamic analysis were performed to determine the impact of seismic load on the diaphragm wall and geotechnical anchors. All geostatic and dynamic numerical (time-history) analysis were performed with finite element method in plain strain conditions (Plaxis 2D) by taking into account the soil-structure interaction. The advanced nonlinear material model with hysteresis damping was adopted for the soil in order to achive adequate soil behavior during seismic loading. The ground data and soil charachteristic taken from the specific location were adopoted for the analyses. Based on the analyses the typical cross-section of diaphragm wall was designed and the results of nonlinear geostatic and dynamic (time-history) analysis were compared. Within the scope of this thesis the comparison between dynamic (time-history) analysis, pseudo-static analysis according to EC-7 and analytical method according to Mononobe-Okabe was performed and results discussed. |
