The impact of shallow cover on tunnelling in soft soil
Shield tunnelling is used widely in constructing underground infrastructure in cities due to the ability to limit settlements and damage to existing buildings. However, in an environment with soft overburden and buildings on pile foundations, the tunnel is often designed well below the pile tip level. There are two reasons for doing this: to reduce interaction between tunnelling process and pil...
متن کاملCover Picture Story: Experiments with Modular State Spaces
The main analysis techniques for critical systems use state space exploration. However, one is often quickly limited by the so-called state space explosion problem, even if the systems models are relatively small. Several methods have been proposed to tackle this problem in order to get a manageable state space. One of these takes advantage of the modular structure of the model in order to buil...
