In this paper, the numerical back analyses of four, typical, monitored deep excavations completed in Budapest are presented. The typical excavation solution in Budapest city center, down to 15–18 m excavation depth, is a diaphragm wall embedded in the clay bedrock and supported by prestressed anchors embedded in the sedimentary soils above the clay...

Mély munkatérhatárolások témakörével foglalkozó doktori kutatási projektünk keretében Budapesten megvalósult munkagödrök mozgásmérési eredményeit rendszereztük és elemeztük. Vizsgálatunk eredményeit jelen publikációban ismertetjük. Bevezetésként összefoglaljuk a munkatárhatárolások deformációinak számítási lehetőségeit és összegezzük a nemzetközi s...

The construction monitoring of Ráckóczi square metro station of Budapest Metro Line 4 offered a great opportunity to back analyse the braced deep excavation in the building period. Building movements, strut forces and wall displacement measurements have been compared to numerical results derived by PLAXIS using HSsmall soil model. Considering the i...

The paper focuses on the numerical back analysis of the monitored deep excavation of II. János Pál pápa square of Budapest Metro Line 4. Inclinometric measurement of diaphragm wall deformations has been compared to numerical results derived by PLAXIS using HSsmall soil model. Considering the influence of small strain stiffness of plastic soils, goo...

The behavior of deep excavation’s retaining structures may become rather complex near the corners. The vicinity of concave corners is an especially problematic zone, and causes numerous problems in everyday practice. Conventional 2D analyses considering axisymmetric or plane strain conditions cannot be used in such cases due the spatial nature of t...
