The influence of different modelling assumptions on the results of numerical analyses of a deep excavation problem is discussed. Based on a reference solution a comprehensive parametric study is performed, identifying modelling assumptions which may have a significant influence on the calculated displacement behaviour and the bending moments in the wall. The parameters investigated include wall...

Stochastic Coherent Adaptive Large-Eddy Simulation is a novel approach to the numerical simulation of turbulence, based upon the wavelet thresholding filter, where the coherent energetic eddies are solved while modelling the influence of the less energetic background flow. In this study, in order to examine the quality and reliability of the method, additional explicit wavelet filtering is intr...
