Abstract

By monitoring and analysing three‐dimensional absolute displacement during tunnel excavation, it is possible to predict discontinuity zones ahead of tunnel face. This paper presents results of the three‐dimensional displacement obtained from three‐dimensional simulations using hybrid method for assessing the effect of discontinuity zones on monitoring data. The influence of fault zones and in situ initial stresses on the three‐dimensional tunnel movement is evaluated. Copyright © 2002 John Wiley & Sons, Ltd.

We present the development and assessment on the accuracy of a perturbative approach for Monte Carlo simulations using a hybrid ab initio quantum mechanical/molecular mechanics (QM/MM) potential. The central idea of this approach is that for most solvent moves, the changes in the solute wavefunction
