摘要

While thermochemomechanical models for the simulation of early-age cement-based materials are nowadays applied to a wide range of engineering problem, allowing to assess the risk of cracking and the level of loading of young concrete, shotcrete, jet-grouted soil,..., the unknown composition of the described materials still introduces uncertainties in the material description which might cause significant errors within the analysis. An adequate tool to introduce mixture variations in material models is provided by the multiscale concept, using the mixture characteristics as input data. Moreover, processes taking place in early-age cement-based materials can be taken into account at the respective scale of observation by adapting the composition and/or the mechanical properties of the constituents. In this paper, the multiscale concept is incorporated into thermochemomechanics of cement-based materials. The so-obtained material model is applied to hybrid analyses of shotcrete tunnel linings, allowing to assess the influence of mixture variations of shotcrete on the level of loading of the lining.
