Back analysis of a shoring system at the excavation site of M4 subway, Budapest
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, good fit of measured and calculated deformations could be observed. Parametric analysis were carried out to observe influence of the following inputs on the numerical results:
Construction time and sequence Consolidation effects Small strain stiffness parameters
A detailed evaluation is given about the results of parametric analysis, considering the inherent errors of the inclinometric measurements, as well.
