3D numerical modelling of brittle failure in mechanized excavation of deep tunnels
For long and deep tunnels as currently under construction through the Alps, mechanised excavation by using Tunnel Boring Machines (TBMs) may contribute significantly to savings in construction times and costs. Questions are however posed due to the severe ground conditions which in cases are …

Hydrologic-hydraulic modeling for the dual drainage and flooding study of the Lawrence Avenue Underflow Sewer System
Urban flooding is generally expected in cities where the urban development increases the impervious surface area which causes the runoff to exceeds the capacity of the drainage system. In the city of Chicago, the Lawrence Avenue Underflow Sewer System (LAUSS) is the first tunnel system built with …
